 To develop components inside this folder there is a particular command: `npm run dev`, this will watch the helpers file and rebuild them with sourcemaps. For this reason remember to build them when done developing.
 
+>While developing components in this library you should execute the test. The `npm test` command will run Jasmine test for the whole complete library.
+>If you want to specify a single test file to be execute, you can add it to the command like: `npm test smart-pie`, the tool will now read only the test specified in the `smart-pie.test.js` file.
+
 When some changes are applied to this common library it should be rebuilt with: `npm run build`
 
 To generate the relative documentation use: `npm run doc`

-      <h1>Hi Matteo!</h1>
-      <h3>Welcome to you development environment.</h3>
-      <p>
-        We provided this environment to help you creating a custom view.
-      </p>
-      <p>
-        When the environment is running you will have an
-        <code>auto-reload</code>
-        feature enabled, so any time you update one of your files, the browser will be reloaded.
-      </p>
-      <p> <i>Note that is environment is already functional and that it is loading information from the XOS APIs and presenting them using the
-          <code>xos-table</code>
-          component.</i> 
-      </p>
-      <h3>Development notes:</h3>
-      <p>
-        This views are designed using
-        <a href="https://angularjs.org/" target="_blank">Angular Js</a>
-        version 1.4.7 and
-        <a href="http://getbootstrap.com/" target="_blank">Bootstrap</a>
-        3.3.6 is included.
-      </p>
-      <p>
-        We just want to remind you that this development environment provide you three helper command:
-        <ul>
-          <li>
-            <code>npm start</code>
-            - will start your setup (you should already be familiar with it)
-          </li>
-          <li>
-            <code>npm test</code>
-            - will execute your unit tests defined with
-            <a href="https://karma-runner.github.io/0.13/index.html" target="_blank">Karma</a>
-            and
-            <a href="jasmine.github.io" target="_blank">Jasmine</a>
-            . You can check the
-            <code>spec/</code>
-            folder to see an example of your first test.
-          </li>
-          <li>
-            <code>npm run build</code>
-            - will build your dashboard and make it available to XOS
-          </li>
-        </ul>
-      </p>
-      <h3>Helpers:</h3>
-      <p>
-        We provide a set of helpers that you can leverage in your dashboard:
-        <ul>
-          <li>
-            <code>xos.helpers</code>
-            - A set of
-            <a href="https://docs.angularjs.org/guide/services" target="_blank">Angular Services</a>
-          </li>
-          <li>
-            <code>xos.uiComponents</code>
-            - A set of
-            <a href="https://docs.angularjs.org/guide/directive" target="_blank">Angular Directives</a>
-          </li>
-          <li>
-            <code>xos.rest</code>
-            - A set of
-            <a href="https://docs.angularjs.org/api/ngResource/service/$resource" target="_blank">Angular $resources</a>
-          </li>
-        </ul>
-        To know more about this helpers you can naviate to
-        <code>/views/ngXosLib/</code>
-        and generate the documentation with
-        <code>npm run doc</code>
-      </p>

+> NOTE: The above script can also automatically perform (nearly) all the steps of this

+### Logging into XOS on CloudLab (or any remote host)
+
+The XOS service is accessible on the POD at `http://xos/`, but `xos` maps to a private IP address
+on the management network.  If you install CORD on CloudLab 
+you will not be able to directly access the XOS GUI.
+In order to log into the XOS GUI in the browser on your local machine (desktop or laptop), 
+you can set up an SSH tunnel to your CloudLab node.  Assuming that 
+`<your-cloudlab-node>` is the DNS name of the CloudLab node hosting your experiment,
+run the following on your local machine to create the tunnel:
+
+```
+$ ssh -L 8888:xos:80 <your-cloudlab-node>
+```
+
+Then you should be able to access the XOS GUI by pointing your browser to
+`http://localhost:8888`.  Default username/password is `padmin@vicci.org/letmein`.

-/**
- * @description
- *
- * This object provides a utility for producing rich Error messages within
- * Angular. It can be called as follows:
- *
- * var exampleMinErr = minErr('example');
- * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
- *
- * The above creates an instance of minErr in the example namespace. The
- * resulting error will have a namespaced error code of example.one.  The
- * resulting error will replace {0} with the value of foo, and {1} with the
- * value of bar. The object is not restricted in the number of arguments it can
- * take.
- *
- * If fewer arguments are specified than necessary for interpolation, the extra
- * interpolation markers will be preserved in the final string.
- *
- * Since data will be parsed statically during a build step, some restrictions
- * are applied with respect to how minErr instances are created and called.
- * Instances should have names of the form namespaceMinErr for a minErr created
- * using minErr('namespace') . Error codes, namespaces and template strings
- * should all be static strings, not variables or general expressions.
- *
- * @param {string} module The namespace to use for the new minErr instance.
- * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
- *   error from returned function, for cases when a particular type of error is useful.
- * @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance

- * @description
- *
- * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
- * designates the **root element** of the application and is typically placed near the root element
- * of the page - e.g. on the `<body>` or `<html>` tags.
- *
- * Only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
- * found in the document will be used to define the root element to auto-bootstrap as an
- * application. To run multiple applications in an HTML document you must manually bootstrap them using
- * {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other.
- *
- * You can specify an **AngularJS module** to be used as the root module for the application.  This
- * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
- * should contain the application code needed or have dependencies on other modules that will
- * contain the code. See {@link angular.module} for more information.
- *
- * In the example below if the `ngApp` directive were not placed on the `html` element then the
- * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
- * would not be resolved to `3`.
- *
- * `ngApp` is the easiest, and most common way to bootstrap an application.
- *
- <example module="ngAppDemo">
-   <file name="index.html">
-   <div ng-controller="ngAppDemoController">

-     * # Module
-     *
-     * A module is a collection of services, directives, controllers, filters, and configuration information.
-     * `angular.module` is used to configure the {@link auto.$injector $injector}.
-     *
-     * ```js
-     * // Create a new module
-     * var myModule = angular.module('myModule', []);
-     *
-     * // register a new service
-     * myModule.value('appName', 'MyCoolApp');
-     *
-     * // configure existing services inside initialization blocks.
-     * myModule.config(['$locationProvider', function($locationProvider) {
-     *   // Configure existing providers
-     *   $locationProvider.hashPrefix('!');
-     * }]);
-     * ```
-     *
-     * Then you can create an injector and load your modules like this:
-     *
-     * ```js
-     * var injector = angular.injector(['ng', 'myModule'])
-     * ```
-     *
-     * However it's more likely that you'll just use

- * @ngdoc function
- * @name angular.element
- * @module ng
- * @kind function
- *
- * @description
- * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
- *
- * If jQuery is available, `angular.element` is an alias for the
- * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
- * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
- *
- * <div class="alert alert-success">jqLite is a tiny, API-compatible subset of jQuery that allows
- * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most
- * commonly needed functionality with the goal of having a very small footprint.</div>
- *
- * To use `jQuery`, simply ensure it is loaded before the `angular.js` file.
- *
- * <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or
- * jqLite; they are never raw DOM references.</div>
- *
- * ## Angular's jqLite
- * jqLite provides only the following jQuery methods:
- *
- * - [`addClass()`](http://api.jquery.com/addClass/)
- * - [`after()`](http://api.jquery.com/after/)
- * - [`append()`](http://api.jquery.com/append/)
- * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
- * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
- * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
- * - [`clone()`](http://api.jquery.com/clone/)
- * - [`contents()`](http://api.jquery.com/contents/)
- * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`. As a setter, does not convert numbers to strings or append 'px'.
- * - [`data()`](http://api.jquery.com/data/)
- * - [`detach()`](http://api.jquery.com/detach/)
- * - [`empty()`](http://api.jquery.com/empty/)
- * - [`eq()`](http://api.jquery.com/eq/)
- * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
- * - [`hasClass()`](http://api.jquery.com/hasClass/)
- * - [`html()`](http://api.jquery.com/html/)

- * ## jQuery/jqLite Extras
- * Angular also provides the following additional methods and events to both jQuery and jqLite:
- *
- * ### Events
- * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
- *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
- *    element before it is removed.
- *
- * ### Methods
- * - `controller(name)` - retrieves the controller of the current element or its parent. By default
- *   retrieves controller associated with the `ngController` directive. If `name` is provided as
- *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
- *   `'ngModel'`).
- * - `injector()` - retrieves the injector of the current element or its parent.
- * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
- *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
- *   be enabled.
- * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
- *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
- *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
- *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
- * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
- *   parent element is reached.
- *
- * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
- * @returns {Object} jQuery object.

- * dependency injection (see {@link guide/di dependency injection}).
- *
- * @param {Array.<string|Function>} modules A list of module functions or their aliases. See
- *     {@link angular.module}. The `ng` module must be explicitly added.
- * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
- *     disallows argument name annotation inference.
- * @returns {injector} Injector object. See {@link auto.$injector $injector}.
- *
- * @example
- * Typical usage
- * ```js
- *   // create an injector
- *   var $injector = angular.injector(['ng']);
- *
- *   // use the injector to kick off your application
- *   // use the type inference to auto inject arguments, or use implicit injection
- *   $injector.invoke(function($rootScope, $compile, $document) {
- *     $compile($document)($rootScope);

- * ```
- *
- * Sometimes you want to get access to the injector of a currently running Angular app
- * from outside Angular. Perhaps, you want to inject and compile some markup after the
- * application has been bootstrapped. You can do this using the extra `injector()` added
- * to JQuery/jqLite elements. See {@link angular.element}.
- *
- * *This is fairly rare but could be the case if a third party library is injecting the
- * markup.*
- *
- * In the following example a new block of HTML containing a `ng-controller`
- * directive is added to the end of the document body by JQuery. We then compile and link
- * it into the current AngularJS scope.
- *
- * ```js
- * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
- * $(document.body).append($div);
- *
- * angular.element(document).injector().invoke(function($compile) {

- * # Injection Function Annotation
- *
- * JavaScript does not have annotations, and annotations are needed for dependency injection. The
- * following are all valid ways of annotating function with injection arguments and are equivalent.
- *
- * ```js
- *   // inferred (only works if code not minified/obfuscated)
- *   $injector.invoke(function(serviceA){});
- *
- *   // annotated
- *   function explicit(serviceA) {};
- *   explicit.$inject = ['serviceA'];
- *   $injector.invoke(explicit);
- *
- *   // inline
- *   $injector.invoke(['serviceA', function(serviceA){}]);
- * ```
- *
- * ## Inference
- *
- * In JavaScript calling `toString()` on a function returns the function definition. The definition
- * can then be parsed and the function arguments can be extracted. This method of discovering
- * annotations is disallowed when the injector is in strict mode.
- * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
- * argument names.
- *
- * ## `$inject` Annotation
- * By adding an `$inject` property onto a function the injection parameters can be specified.
- *
- * ## Inline
- * As an array of injection names, where the last item in the array is the function to call.

- * This method does not work with code minification / obfuscation. For this reason the following
- * annotation strategies are supported.
- *
- * # The `$inject` property
- *
- * If a function has an `$inject` property and its value is an array of strings, then the strings
- * represent names of services to be injected into the function.
- * ```js
- *   // Given
- *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
- *     // ...
- *   }
- *   // Define function dependencies
- *   MyController['$inject'] = ['$scope', '$route'];
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * # The array notation
- *
- * It is often desirable to inline Injected functions and that's when setting the `$inject` property
- * is very inconvenient. In these situations using the array notation to specify the dependencies in
- * a way that survives minification is a better choice:
- *
- * ```js
- *   // We wish to write this (not minification / obfuscation safe)
- *   injector.invoke(function($compile, $rootScope) {
- *     // ...
- *   });
- *
- *   // We are forced to write break inlining
- *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
- *     // ...
- *   };
- *   tmpFn.$inject = ['$compile', '$rootScope'];
- *   injector.invoke(tmpFn);
- *
- *   // To better support inline function the inline annotation is supported
- *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
- *     // ...
- *   }]);
- *
- *   // Therefore
- *   expect(injector.annotate(
- *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
- *    ).toEqual(['$compile', '$rootScope']);
- * ```
- *
- * @param {Function|Array.<string|Function>} fn Function for which dependent service names need to
- * be retrieved as described above.
- *
- * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
- *
- * @returns {Array.<string>} The names of the services which the function requires.

- * @ngdoc service
- * @name $provide
- *
- * @description
- *
- * The {@link auto.$provide $provide} service has a number of methods for registering components
- * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
- * {@link angular.Module}.
- *
- * An Angular **service** is a singleton object created by a **service factory**.  These **service
- * factories** are functions which, in turn, are created by a **service provider**.
- * The **service providers** are constructor functions. When instantiated they must contain a
- * property called `$get`, which holds the **service factory** function.
- *
- * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
- * correct **service provider**, instantiating it and then calling its `$get` **service factory**
- * function to get the instance of the **service**.
- *
- * Often services have no configuration options and there is no need to add methods to the service
- * provider.  The provider will be no more than a constructor function with a `$get` property. For
- * these cases the {@link auto.$provide $provide} service has additional helper methods to register
- * services without specifying a provider.
- *
- * * {@link auto.$provide#provider provider(provider)} - registers a **service provider** with the
- *     {@link auto.$injector $injector}
- * * {@link auto.$provide#constant constant(obj)} - registers a value/object that can be accessed by
- *     providers and services.
- * * {@link auto.$provide#value value(obj)} - registers a value/object that can only be accessed by
- *     services, not providers.
- * * {@link auto.$provide#factory factory(fn)} - registers a service **factory function**, `fn`,
- *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
- *     given factory function.
- * * {@link auto.$provide#service service(class)} - registers a **constructor function**, `class`
- *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
- *      a new object using the given constructor function.
- *
- * See the individual methods for more information and examples.

-/**
- * @ngdoc method
- * @name $provide#provider
- * @description
- *
- * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
- * are constructor functions, whose instances are responsible for "providing" a factory for a
- * service.
- *
- * Service provider names start with the name of the service they provide followed by `Provider`.
- * For example, the {@link ng.$log $log} service has a provider called
- * {@link ng.$logProvider $logProvider}.
- *
- * Service provider objects can have additional methods which allow configuration of the provider
- * and its service. Importantly, you can configure what kind of service is created by the `$get`
- * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
- * method {@link ng.$logProvider#debugEnabled debugEnabled}
- * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
- * console or not.
- *
- * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
-                        'Provider'` key.
- * @param {(Object|function())} provider If the provider is:
- *
- *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
- *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
- *   - `Constructor`: a new instance of the provider will be created using
- *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
- *
- * @returns {Object} registered provider instance
-
- * @example
- *
- * The following example shows how to create a simple event tracking service and register it using
- * {@link auto.$provide#provider $provide.provider()}.
- *
- * ```js
- *  // Define the eventTracker provider
- *  function EventTrackerProvider() {
- *    var trackingUrl = '/track';
- *
- *    // A provider method for configuring where the tracked events should been saved
- *    this.setTrackingUrl = function(url) {
- *      trackingUrl = url;
- *    };
- *
- *    // The service factory function
- *    this.$get = ['$http', function($http) {
- *      var trackedEvents = {};
- *      return {
- *        // Call this to track an event
- *        event: function(event) {
- *          var count = trackedEvents[event] || 0;
- *          count += 1;
- *          trackedEvents[event] = count;
- *          return count;
- *        },
- *        // Call this to save the tracked events to the trackingUrl
- *        save: function() {
- *          $http.post(trackingUrl, trackedEvents);
- *        }
- *      };
- *    }];
- *  }

- *    var postSpy;
- *
- *    beforeEach(module(function($provide) {
- *      // Register the eventTracker provider
- *      $provide.provider('eventTracker', EventTrackerProvider);
- *    }));
- *
- *    beforeEach(module(function(eventTrackerProvider) {
- *      // Configure eventTracker provider
- *      eventTrackerProvider.setTrackingUrl('/custom-track');
- *    }));
- *

- *      expect(eventTracker.event('login')).toEqual(1);
- *      expect(eventTracker.event('login')).toEqual(2);

-   *
-   * @description
-   * When called, it scrolls to the element related to the specified `hash` or (if omitted) to the
-   * current value of {@link ng.$location#hash $location.hash()}, according to the rules specified
-   * in the
-   * [HTML5 spec](http://dev.w3.org/html5/spec/Overview.html#the-indicated-part-of-the-document).
-   *
-   * It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
-   * match any anchor whenever it changes. This can be disabled by calling
-   * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
-   *
-   * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
-   * vertical scroll-offset (either fixed or dynamic).
-   *
-   * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
-   *                       {@link ng.$location#hash $location.hash()} will be used.
-   *
-   * @property {(number|function|jqLite)} yOffset
-   * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
-   * positioned elements at the top of the page, such as navbars, headers etc.
-   *
-   * `yOffset` can be specified in various ways:
-   * - **number**: A fixed number of pixels to be used as offset.<br /><br />
-   * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
-   *   a number representing the offset (in pixels).<br /><br />
-   * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
-   *   the top of the page to the element's bottom will be used as offset.<br />
-   *   **Note**: The element will be taken into account only as long as its `position` is set to
-   *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
-   *   their height and/or positioning according to the viewport's size.
-   *
-   * <br />
-   * <div class="alert alert-warning">
-   * In order for `yOffset` to work properly, scrolling should take place on the document's root and
-   * not some child element.

-     * @description The $animate service exposes a series of DOM utility methods that provide support
-     * for animation hooks. The default behavior is the application of DOM operations, however,
-     * when an animation is detected (and animations are enabled), $animate will do the heavy lifting
-     * to ensure that animation runs with the triggered DOM operation.
-     *
-     * By default $animate doesn't trigger an animations. This is because the `ngAnimate` module isn't
-     * included and only when it is active then the animation hooks that `$animate` triggers will be
-     * functional. Once active then all structural `ng-` directives will trigger animations as they perform
-     * their DOM-related operations (enter, leave and move). Other directives such as `ngClass`,
-     * `ngShow`, `ngHide` and `ngMessages` also provide support for animations.
-     *
-     * It is recommended that the`$animate` service is always used when executing DOM-related procedures within directives.
-     *

-     * {@link ngAnimate ngAnimate module page}.

-/**
- * @ngdoc service
- * @name $compile
- * @kind function
- *
- * @description
- * Compiles an HTML string or DOM into a template and produces a template function, which
- * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
- *
- * The compilation is a process of walking the DOM tree and matching DOM elements to
- * {@link ng.$compileProvider#directive directives}.
- *
- * <div class="alert alert-warning">
- * **Note:** This document is an in-depth reference of all directive options.
- * For a gentle introduction to directives with examples of common use cases,
- * see the {@link guide/directive directive guide}.
- * </div>
- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a "Directive Definition Object" (see below) that defines the directive properties,
- * or just the `postLink` function (all other properties will have the default values).
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's recommended to use the "directive definition object" form.
- * </div>
- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       priority: 0,
- *       template: '<div></div>', // or // function(tElement, tAttrs) { ... },
- *       // or
- *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
- *       transclude: false,
- *       restrict: 'A',
- *       templateNamespace: 'html',
- *       scope: false,
- *       controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
- *       controllerAs: 'stringIdentifier',
- *       bindToController: false,
- *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
- *       compile: function compile(tElement, tAttrs, transclude) {
- *         return {
- *           pre: function preLink(scope, iElement, iAttrs, controller) { ... },
- *           post: function postLink(scope, iElement, iAttrs, controller) { ... }
- *         }
- *         // or
- *         // return function postLink( ... ) { ... }
- *       },
- *       // or
- *       // link: {
- *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... },
- *       //  post: function postLink(scope, iElement, iAttrs, controller) { ... }
- *       // }
- *       // or
- *       // link: function postLink( ... ) { ... }
- *     };
- *     return directiveDefinitionObject;
- *   });
- * ```
- *
- * <div class="alert alert-warning">
- * **Note:** Any unspecified options will use the default value. You can see the default values below.
- * </div>
- *
- * Therefore the above can be simplified as:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       link: function postLink(scope, iElement, iAttrs) { ... }
- *     };
- *     return directiveDefinitionObject;
- *     // or
- *     // return function postLink(scope, iElement, iAttrs) { ... }
- *   });
- * ```
- *
- *
- *
- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the {@link ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true, the HTML compiler will collect DOM nodes between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
- * together as the directive elements. It is recommended that this feature be used on directives
- * which are not strictly behavioural (such as {@link ngClick}), and which
- * do not manipulate or replace child nodes (such as {@link ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, sometimes it
- * is necessary to specify the order in which the directives are applied. The `priority` is used
- * to sort the directives before their `compile` functions get called. Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse order. The order
- * of directives with the same priority is undefined. The default priority is `0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of directives
- * which will execute (any directives at the current priority will still execute
- * as the order of execution on same `priority` is undefined). Note that expressions
- * and other directives used in the directive's template will also be excluded from execution.
- *
- * #### `scope`
- * The scope property can be `true`, an object or a falsy value:
- *
- * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.
- *
- * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
- * the directive's element. If multiple directives on the same element request a new scope,
- * only one new scope is created. The new scope rule does not apply for the root of the template
- * since the root of the template always gets a new scope.
- *
- * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
- * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
- * scope. This is useful when creating reusable components, which should not accidentally read or modify
- * data in the parent scope.
- *
- * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
- * directive's element. These local properties are useful for aliasing values for templates. The keys in
- * the object hash map to the name of the property on the isolate scope; the values define how the property
- * is bound to the parent scope, via matching attributes on the directive's element:
- *
- * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
- *   always a string since DOM attributes are strings. If no `attr` name is specified  then the
- *   attribute name is assumed to be the same as the local name.
- *   Given `<widget my-attr="hello {{name}}">` and widget definition
- *   of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect
- *   the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the
- *   `localName` property on the widget scope. The `name` is read from the parent scope (not
- *   component scope).
- *
- * * `=` or `=attr` - set up bi-directional binding between a local scope property and the
- *   parent scope property of name defined via the value of the `attr` attribute. If no `attr`
- *   name is specified then the attribute name is assumed to be the same as the local name.
- *   Given `<widget my-attr="parentModel">` and widget definition of
- *   `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the
- *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
- *   in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent
- *   scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You
- *   can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. If
- *   you want to shallow watch for changes (i.e. $watchCollection instead of $watch) you can use
- *   `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional).
- *
- * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.
- *   If no `attr` name is specified then the attribute name is assumed to be the same as the
- *   local name. Given `<widget my-attr="count = count + value">` and widget definition of
- *   `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to
- *   a function wrapper for the `count = count + value` expression. Often it's desirable to
- *   pass data from the isolated scope via an expression to the parent scope, this can be
- *   done by passing a map of local variable names and values into the expression wrapper fn.
- *   For example, if the expression is `increment(amount)` then we can specify the amount value
- *   by calling the `localFn` as `localFn({amount: 22})`.
- *
- * In general it's possible to apply more than one directive to one element, but there might be limitations
- * depending on the type of scope required by the directives. The following points will help explain these limitations.
- * For simplicity only two directives are taken into account, but it is also applicable for several directives:
- *
- * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
- * * **child scope** + **no scope** =>  Both directives will share one single child scope
- * * **child scope** + **child scope** =>  Both directives will share one single child scope
- * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
- * its parent's scope
- * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
- * be applied to the same element.
- * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
- * cannot be applied to the same element.
- *
- *
- * #### `bindToController`
- * When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController: true` will
- * allow a component to have its properties bound to the controller, rather than to scope. When the controller
- * is instantiated, the initial values of the isolate scope bindings are already available.
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and can be accessed by other directives (see
- * `require` attribute). This allows the directives to communicate with each other and augment
- * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
- *   `function([scope], cloneLinkingFn, futureParentElement)`.
- *    * `scope`: optional argument to override the scope.
- *    * `cloneLinkingFn`: optional argument to create clones of the original transcluded content.
- *    * `futureParentElement`:
- *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
- *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
- *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
- *          and when the `cloneLinkinFn` is passed,
- *          as those elements need to created and cloned in a special way when they are defined outside their
- *          usual containers (e.g. like `<svg>`).
- *        * See also the `directive.templateNamespace` property.
- *
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument to the linking function. The
- * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the
- * injected argument will be an array in corresponding order. If no such directive can be
- * found, or if the directive does not have a controller, then an error is raised (unless no link function
- * is specified, in which case error checking is skipped). The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
- * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
- *   `null` to the `link` fn if not found.
- * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
- *   `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Identifier name for a reference to the controller in the directive's scope.
- * This allows the controller to be referenced from the directive template. This is especially
- * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
- * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
- * `controllerAs` reference might overwrite a property that already exists on the parent scope.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific directive
- * declaration style. If omitted, the defaults (elements and attributes) are used.
- *
- * * `E` - Element name (default): `<my-directive></my-directive>`
- * * `A` - Attribute (default): `<div my-directive="exp"></div>`
- * * `C` - Class: `<div class="my-directive: exp;"></div>`
- * * `M` - Comment: `<!-- directive: my-directive exp -->`
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and cloned
- * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- *   top-level elements such as `<svg>` or `<math>`.
- * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
- * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
- *   function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
- * for later when the template has been resolved.  In the meantime it will continue to compile and link
- * sibling and parent elements as though this element had not contained any directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
- * a string value representing the url.  In either case, the template URL is passed through {@link
- * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
- * specify what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's element.
- *
- * The replacement process migrates all of the attributes / classes from the old element to the new
- * one. See the {@link guide/directive#template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the application function,
- * the main one being reusable custom components that are used within SVG contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * Extract the contents of the element where the directive appears and make it available to the directive.
- * The contents are compiled and provided to the directive as a **transclusion function**. See the
- * {@link $compile#transclusion Transclusion} section below.
- *
- * There are two kinds of transclusion depending upon whether you want to transclude just the contents of the
- * directive's element or the entire element:
- *
- * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
- * * `'element'` - transclude the whole of the directive's element including any directives on this
- *   element that defined at a lower priority than this directive. When used, the `template`
- *   property is ignored.
- *
- *
- * #### `compile`
- *
- * ```js
- *   function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most directives do not do
- * template transformation, it is not used often. The compile function takes the following arguments:
- *
- *   * `tElement` - template element - The element where the directive has been declared. It is
- *     safe to do template transformation on the element and child elements only.
- *
- *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
- *     between all directive compile functions.
- *
- *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
- *
- * <div class="alert alert-warning">
- * **Note:** The template instance and the link instance may be different objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
- * should be done in a linking function rather than in a compile function.
- * </div>
-
- * <div class="alert alert-warning">
- * **Note:** The compile function cannot handle directives that recursively use themselves in their
- * own templates or compile functions. Compiling these directives results in an infinite loop and a
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to imperatively compile
- * a directive's template instead of relying on automatic template compilation via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- * </div>
- *
- * <div class="alert alert-danger">
- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
- *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
- *   to the link function instead.
- * </div>
-
- * A compile function can have a return value which can be either a function or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the linking function via the
- *   `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
- *   control when a linking function should be called during the linking phase. See info about
- *   pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
- * executed after the template has been cloned. This is where most of the directive logic will be
- * put.
- *
- *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
- *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
- *
- *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
- *     manipulate the children of the element only in `postLink` function since the children have
- *     already been linked.
- *
- *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
- *     between all directive linking functions.
- *
- *   * `controller` - the directive's required controller instance(s) - Instances are shared
- *     among all directives, which allows the directives to use the controllers as a communication
- *     channel. The exact value depends on the directive's `require` property:
- *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
- *       * `string`: the controller instance
- *       * `array`: array of controller instances
- *
- *     If a required controller cannot be found, and it is optional, the instance is `null`,
- *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
- *
- *     Note that you can also require the directive's own controller - it will be made available like
- *     any other controller.
- *
- *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
- *     This is the same as the `$transclude`
- *     parameter of directive controllers, see there for details.
- *     `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM transformation since the
- * compiler linking function will fail to locate the correct elements for linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not have been compiled
- * and linked since they are waiting for their template to load asynchronously and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
- * for their async templates to be resolved.
- *
- *
- * ### Transclusion
- *
- * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
- * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
- * scope from where they were taken.
- *
- * Transclusion is used (often with {@link ngTransclude}) to insert the
- * original contents of a directive's element into a specified place in the template of the directive.
- * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
- * content has access to the properties on the scope from which it was taken, even if the directive
- * has isolated scope.
- * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
- *
- * This makes it possible for the widget to have private state for its template, while the transcluded
- * content has access to its originating scope.
- *
- * <div class="alert alert-warning">
- * **Note:** When testing an element transclude directive you must not place the directive at the root of the
- * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- * </div>
- *
- * #### Transclusion Functions
- *
- * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
- * function** to the directive's `link` function and `controller`. This transclusion function is a special
- * **linking function** that will return the compiled contents linked to a new transclusion scope.
- *
- * <div class="alert alert-info">
- * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
- * ngTransclude will deal with it for us.
- * </div>
- *
- * If you want to manually control the insertion and removal of the transcluded content in your directive
- * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
- * object that contains the compiled DOM, which is linked to the correct transclusion scope.
- *
- * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
- * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
- * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
- *
- * <div class="alert alert-info">
- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a translude function
- * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
- * </div>
- *
- * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
- * attach function**:
- *
- * ```js
- * var transcludedContent, transclusionScope;
- *
- * $transclude(function(clone, scope) {
- *   element.append(clone);
- *   transcludedContent = clone;
- *   transclusionScope = scope;
- * });
- * ```
- *
- * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
- * associated transclusion scope:
- *
- * ```js
- * transcludedContent.remove();
- * transclusionScope.$destroy();
- * ```
- *
- * <div class="alert alert-info">
- * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
- * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
- * then you are also responsible for calling `$destroy` on the transclusion scope.
- * </div>
- *
- * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
- * automatically destroy their transluded clones as necessary so you do not need to worry about this if
- * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
- *
- *
- * #### Transclusion Scopes
- *
- * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
- * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
- * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
- * was taken.
- *
- * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
- * like this:
- *
- * ```html
- * <div ng-app>
- *   <div isolate>
- *     <div transclusion>
- *     </div>
- *   </div>
- * </div>
- * ```
- *
- * The `$parent` scope hierarchy will look like this:
- *
- * ```
- * - $rootScope
- *   - isolate
- *     - transclusion
- * ```
- *
- * but the scopes will inherit prototypically from different scopes to their `$parent`.
- *
- * ```
- * - $rootScope
- *   - transclusion
- * - isolate
- * ```
- *
- *
- * ### Attributes
- *
- * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * accessing *Normalized attribute names:*
- * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.
- * the attributes object allows for normalized access to
- *   the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance of the attributes
- *   object which allows the directives to use the attributes object as inter directive
- *   communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
- *   allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
- *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
- *   the only way to easily get the actual value because during the linking phase the interpolation
- *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- *   // get the attribute value
- *   console.log(attrs.ngModel);
- *
- *   // change the attribute
- *   attrs.$set('ngModel', 'new value');
- *
- *   // observe changes to interpolated attribute
- *   attrs.$observe('ngModel', function(value) {
- *     console.log('ngModel has changed value to ' + value);
- *   });
- * }
- * ```
- *
- * ## Example
- *
- * <div class="alert alert-warning">
- * **Note**: Typically directives are registered with `module.directive`. The example below is
- * to illustrate how `$compile` works.
- * </div>
- *
- <example module="compileExample">
-   <file name="index.html">
-    <script>
-      angular.module('compileExample', [], function($compileProvider) {
-        // configure new 'compile' directive by passing a directive
-        // factory function. The factory function injects the '$compile'
-        $compileProvider.directive('compile', function($compile) {
-          // directive factory creates a link function
-          return function(scope, element, attrs) {
-            scope.$watch(
-              function(scope) {
-                 // watch the 'compile' expression for changes
-                return scope.$eval(attrs.compile);
-              },
-              function(value) {
-                // when the 'compile' expression changes
-                // assign it into the current DOM
-                element.html(value);
-
-                // compile the new DOM and link it to the current
-                // scope.
-                // NOTE: we only compile .childNodes so that
-                // we don't get into infinite loop compiling ourselves
-                $compile(element.contents())(scope);
-              }
-            );
-          };
-        });
-      })
-      .controller('GreeterController', ['$scope', function($scope) {
-        $scope.name = 'Angular';
-        $scope.html = 'Hello {{name}}';
-      }]);
-    </script>
-    <div ng-controller="GreeterController">
-      <input ng-model="name"> <br/>
-      <textarea ng-model="html"></textarea> <br/>
-      <div compile="html"></div>
-    </div>
-   </file>
-   <file name="protractor.js" type="protractor">
-     it('should auto compile', function() {
-       var textarea = $('textarea');
-       var output = $('div[compile]');
-       // The initial state reads 'Hello Angular'.
-       expect(output.getText()).toBe('Hello Angular');
-       textarea.clear();
-       textarea.sendKeys('{{name}}!');
-       expect(output.getText()).toBe('Angular!');
-     });
-   </file>
- </example>
-
- *
- *
- * @param {string|DOMElement} element Element or HTML string to compile into a template function.
- * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
- *
- * <div class="alert alert-danger">
- * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
- *   e.g. will not use the right outer scope. Please pass the transclude function as a
- *   `parentBoundTranscludeFn` to the link function instead.
- * </div>
- *
- * @param {number} maxPriority only apply directives lower than given priority (Only effects the
- *                 root element(s), not their children)
- * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
- * (a DOM element/tree) to a scope. Where:
- *
- *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
- *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
- *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
- *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
- *  called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
- *
- *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
- *      * `scope` - is the current scope with which the linking function is working with.
- *
- *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
- *  keys may be used to control linking behavior:
- *
- *      * `parentBoundTranscludeFn` - the transclude function made available to
- *        directives; if given, it will be passed through to the link functions of
- *        directives found in `element` during compilation.
- *      * `transcludeControllers` - an object hash with keys that map controller names
- *        to controller instances; if given, it will make the controllers
- *        available to directives.
- *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
- *        the cloned elements; only needed for transcludes that are allowed to contain non html
- *        elements (e.g. SVG elements). See also the directive.controller property.
- *
- * Calling the linking function returns the element of the template. It is either the original
- * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
- *
- * After linking the view is not updated until after a call to $digest which typically is done by
- * Angular automatically.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create the DOM element(s)
- *   before you send them to the compiler and keep this reference around.
- *   ```js
- *     var element = $compile('<p>{{total}}</p>')(scope);
- *   ```
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- *   example would not point to the clone, but rather to the original template that was cloned. In
- *   this case, you can access the clone via the cloneAttachFn:
- *   ```js
- *     var templateElement = angular.element('<p>{{total}}</p>'),
- *         scope = ....;
- *
- *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
- *       //attach the clone to DOM document at the right place
- *     });
- *
- *     //now we have reference to the cloned DOM via `clonedElement`
- *   ```
- *
- *
- * For information on how the compiler works, see the
- * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

- * @ngdoc service
- * @name $exceptionHandler
- * @requires ng.$log
- *
- * @description
- * Any uncaught exception in angular expressions is delegated to this service.
- * The default implementation simply delegates to `$log.error` which logs it into
- * the browser console.
- *
- * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
- * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
- *
- * ## Example:
- *
- * ```js
- *   angular.module('exceptionOverride', []).factory('$exceptionHandler', function() {
- *     return function(exception, cause) {
- *       exception.message += ' (caused by "' + cause + '")';
- *       throw exception;
- *     };
- *   });
- * ```
- *
- * This example will override the normal action of `$exceptionHandler`, to make angular
- * exceptions fail hard when they happen, instead of just logging to the console.
- *
- * <hr />
- * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
- * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
- * (unless executed during a digest).
- *
- * If you wish, you can manually delegate exceptions, e.g.
- * `try { ... } catch(e) { $exceptionHandler(e); }`
- *
- * @param {Error} exception Exception associated with the error.
- * @param {string=} cause optional information about the context in which
- *       the error was thrown.

-     * @description
-     * The `$http` service is a core Angular service that facilitates communication with the remote
-     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
-     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
-     *
-     * For unit testing applications that use `$http` service, see
-     * {@link ngMock.$httpBackend $httpBackend mock}.
-     *
-     * For a higher level of abstraction, please check out the {@link ngResource.$resource
-     * $resource} service.
-     *
-     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
-     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
-     * it is important to familiarize yourself with these APIs and the guarantees they provide.
-     *
-     *
-     * ## General usage
-     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
-     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}.
-     *
-     * ```js
-     *   // Simple GET request example:
-     *   $http({
-     *     method: 'GET',
-     *     url: '/someUrl'
-     *   }).then(function successCallback(response) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }, function errorCallback(response) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
-     *
-     * The response object has these properties:
-     *
-     *   - **data** – `{string|Object}` – The response body transformed with the transform
-     *     functions.
-     *   - **status** – `{number}` – HTTP status code of the response.
-     *   - **headers** – `{function([headerName])}` – Header getter function.
-     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
-     *   - **statusText** – `{string}` – HTTP status text of the response.
-     *
-     * A response status code between 200 and 299 is considered a success status and
-     * will result in the success callback being called. Note that if the response is a redirect,
-     * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
-     * called for such responses.
-     *
-     *
-     * ## Shortcut methods
-     *
-     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
-     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
-     * last argument.
-     *
-     * ```js
-     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
-     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
-     * ```
-     *
-     * Complete list of shortcut methods:
-     *
-     * - {@link ng.$http#get $http.get}
-     * - {@link ng.$http#head $http.head}
-     * - {@link ng.$http#post $http.post}
-     * - {@link ng.$http#put $http.put}
-     * - {@link ng.$http#delete $http.delete}
-     * - {@link ng.$http#jsonp $http.jsonp}
-     * - {@link ng.$http#patch $http.patch}
-     *
-     *
-     * ## Writing Unit Tests that use $http
-     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
-     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
-     * request using trained responses.
-     *
-     * ```
-     * $httpBackend.expectGET(...);
-     * $http.get(...);
-     * $httpBackend.flush();
-     * ```
-     *
-     * ## Deprecation Notice
-     * <div class="alert alert-danger">
-     *   The `$http` legacy promise methods `success` and `error` have been deprecated.
-     *   Use the standard `then` method instead.
-     *   If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
-     *   `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
-     * </div>
-     *
-     * ## Setting HTTP Headers
-     *
-     * The $http service will automatically add certain HTTP headers to all requests. These defaults
-     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
-     * object, which currently contains this default configuration:
-     *
-     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
-     *   - `Accept: application/json, text/plain, * / *`
-     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
-     *   - `Content-Type: application/json`
-     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
-     *   - `Content-Type: application/json`
-     *
-     * To add or overwrite these defaults, simply add or remove a property from these configuration
-     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
-     * with the lowercased HTTP method name as the key, e.g.
-     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
-     *
-     * The defaults can also be set at runtime via the `$http.defaults` object in the same
-     * fashion. For example:
-     *
-     * ```
-     * module.run(function($http) {
-     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'
-     * });
-     * ```
-     *
-     * In addition, you can supply a `headers` property in the config object passed when
-     * calling `$http(config)`, which overrides the defaults without changing them globally.
-     *
-     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
-     * Use the `headers` property, setting the desired header to `undefined`. For example:
-     *
-     * ```js
-     * var req = {
-     *  method: 'POST',
-     *  url: 'http://example.com',
-     *  headers: {
-     *    'Content-Type': undefined
-     *  },
-     *  data: { test: 'test' }
-     * }
-     *
-     * $http(req).then(function(){...}, function(){...});
-     * ```
-     *
-     * ## Transforming Requests and Responses
-     *
-     * Both requests and responses can be transformed using transformation functions: `transformRequest`
-     * and `transformResponse`. These properties can be a single function that returns
-     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
-     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
-     *
-     * ### Default Transformations
-     *
-     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
-     * `defaults.transformResponse` properties. If a request does not provide its own transformations
-     * then these will be applied.
-     *
-     * You can augment or replace the default transformations by modifying these properties by adding to or
-     * replacing the array.
-     *
-     * Angular provides the following default transformations:
-     *
-     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
-     *
-     * - If the `data` property of the request configuration object contains an object, serialize it
-     *   into JSON format.
-     *
-     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
-     *
-     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
-     *  - If JSON response is detected, deserialize it using a JSON parser.
-     *
-     *
-     * ### Overriding the Default Transformations Per Request
-     *
-     * If you wish override the request/response transformations only for a single request then provide
-     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
-     * into `$http`.
-     *
-     * Note that if you provide these properties on the config object the default transformations will be
-     * overwritten. If you wish to augment the default transformations then you must include them in your
-     * local transformation array.
-     *
-     * The following code demonstrates adding a new response transformation to be run after the default response
-     * transformations have been run.
-     *
-     * ```js
-     * function appendTransform(defaults, transform) {
-     *
-     *   // We can't guarantee that the default transformation is an array
-     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
-     *
-     *   // Append the new transformation to the defaults
-     *   return defaults.concat(transform);
-     * }
-     *
-     * $http({
-     *   url: '...',
-     *   method: 'GET',
-     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
-     *     return doTransform(value);
-     *   })
-     * });
-     * ```
-     *
-     *
-     * ## Caching
-     *
-     * To enable caching, set the request configuration `cache` property to `true` (to use default
-     * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).
-     * When the cache is enabled, `$http` stores the response from the server in the specified
-     * cache. The next time the same request is made, the response is served from the cache without
-     * sending a request to the server.
-     *
-     * Note that even if the response is served from cache, delivery of the data is asynchronous in
-     * the same way that real requests are.
-     *
-     * If there are multiple GET requests for the same URL that should be cached using the same
-     * cache, but the cache is not populated yet, only one request to the server will be made and
-     * the remaining requests will be fulfilled using the response from the first request.
-     *
-     * You can change the default cache to a new object (built with
-     * {@link ng.$cacheFactory `$cacheFactory`}) by updating the
-     * {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set
-     * their `cache` property to `true` will now use this cache object.
-     *
-     * If you set the default cache to `false` then only requests that specify their own custom
-     * cache object will be cached.
-     *
-     * ## Interceptors
-     *
-     * Before you start creating interceptors, be sure to understand the
-     * {@link ng.$q $q and deferred/promise APIs}.
-     *
-     * For purposes of global error handling, authentication, or any kind of synchronous or
-     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
-     * able to intercept requests before they are handed to the server and
-     * responses before they are handed over to the application code that
-     * initiated these requests. The interceptors leverage the {@link ng.$q
-     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
-     *
-     * The interceptors are service factories that are registered with the `$httpProvider` by
-     * adding them to the `$httpProvider.interceptors` array. The factory is called and
-     * injected with dependencies (if specified) and returns the interceptor.
-     *
-     * There are two kinds of interceptors (and two kinds of rejection interceptors):
-     *
-     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
-     *     modify the `config` object or create a new one. The function needs to return the `config`
-     *     object directly, or a promise containing the `config` or a new `config` object.
-     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *   * `response`: interceptors get called with http `response` object. The function is free to
-     *     modify the `response` object or create a new one. The function needs to return the `response`
-     *     object directly, or as a promise containing the `response` or a new `response` object.
-     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *
-     *
-     * ```js
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
-     *     return {
-     *       // optional method
-     *       'request': function(config) {
-     *         // do something on success
-     *         return config;
-     *       },
-     *
-     *       // optional method
-     *      'requestError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       },
-     *
-     *
-     *
-     *       // optional method
-     *       'response': function(response) {
-     *         // do something on success
-     *         return response;
-     *       },
-     *
-     *       // optional method
-     *      'responseError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       }
-     *     };
-     *   });
-     *
-     *   $httpProvider.interceptors.push('myHttpInterceptor');
-     *
-     *
-     *   // alternatively, register the interceptor via an anonymous factory
-     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
-     *     return {
-     *      'request': function(config) {
-     *          // same as above
-     *       },
-     *
-     *       'response': function(response) {
-     *          // same as above
-     *       }
-     *     };
-     *   });
-     * ```
-     *
-     * ## Security Considerations
-     *
-     * When designing web applications, consider security threats from:
-     *
-     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
-     *
-     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
-     * pre-configured with strategies that address these issues, but for this to work backend server
-     * cooperation is required.
-     *
-     * ### JSON Vulnerability Protection
-     *
-     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * allows third party website to turn your JSON resource URL into
-     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
-     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
-     * Angular will automatically strip the prefix before processing it as JSON.
-     *
-     * For example if your server needs to return:
-     * ```js
-     * ['one','two']
-     * ```
-     *
-     * which is vulnerable to attack, your server can return:
-     * ```js
-     * )]}',
-     * ['one','two']
-     * ```
-     *
-     * Angular will strip the prefix, before processing the JSON.
-     *
-     *
-     * ### Cross Site Request Forgery (XSRF) Protection
-     *
-     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which
-     * an unauthorized site can gain your user's private data. Angular provides a mechanism
-     * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
-     * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only
-     * JavaScript that runs on your domain could read the cookie, your server can be assured that
-     * the XHR came from JavaScript running on your domain. The header will not be set for
-     * cross-domain requests.
-     *
-     * To take advantage of this, your server needs to set a token in a JavaScript readable session
-     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
-     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
-     * that only JavaScript running on your domain could have sent the request. The token must be
-     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
-     * making up its own tokens). We recommend that the token is a digest of your site's
-     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
-     * for added security.
-     *
-     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
-     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
-     * or the per-request config object.
-     *
-     * In order to prevent collisions in environments where multiple Angular apps share the
-     * same domain or subdomain, we recommend that each application uses unique cookie name.
-     *
-     * @param {object} config Object describing the request to be made and how it should be
-     *    processed. The object has following properties:
-     *
-     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
-     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
-     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
-     *      with the `paramSerializer` and appended as GET parameters.
-     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
-     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
-     *      HTTP headers to send to the server. If the return value of a function is null, the
-     *      header will not be sent. Functions accept a config object as an argument.
-     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
-     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
-     *    - **transformRequest** –
-     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      request body and headers and returns its transformed (typically serialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **transformResponse** –
-     *      `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      response body, headers and status and returns its transformed (typically deserialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default TransformationjqLiks}
-     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
-     *      prepare the string representation of request parameters (specified as an object).
-     *      If specified as string, it is interpreted as function registered with the
-     *      {@link $injector $injector}, which means you can create your own serializer
-     *      by registering it as a {@link auto.$provide#service service}.
-     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
-     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
-     *    - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
-     *      GET request, otherwise if a cache instance built with
-     *      {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
-     *      caching.
-     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
-     *      that should abort the request when resolved.
-     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
-     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
-     *      for more information.
-     *    - **responseType** - `{string}` - see
-     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
-     *
-     * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
-     *                        when the request succeeds or fails.
-     *
-     *
-     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
-     *   requests. This is primarily meant to be used for debugging purposes.
-     *

-     *
-     * @description
-     *
-     * Compiles a string with markup into an interpolation function. This service is used by the
-     * HTML {@link ng.$compile $compile} service for data binding. See
-     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
-     * interpolation markup.
-     *
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var exp = $interpolate('Hello {{name | uppercase}}!');
-     *   expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
-     * ```
-     *
-     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
-     * `true`, the interpolation function will return `undefined` unless all embedded expressions
-     * evaluate to a value other than `undefined`.
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var context = {greeting: 'Hello', name: undefined };
-     *
-     *   // default "forgiving" mode
-     *   var exp = $interpolate('{{greeting}} {{name}}!');
-     *   expect(exp(context)).toEqual('Hello !');
-     *
-     *   // "allOrNothing" mode
-     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
-     *   expect(exp(context)).toBeUndefined();
-     *   context.name = 'Angular';
-     *   expect(exp(context)).toEqual('Hello Angular!');
-     * ```
-     *
-     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
-     *
-     * ####Escaped Interpolation
-     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
-     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
-     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
-     * or binding.
-     *
-     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
-     * degree, while also enabling code examples to work without relying on the
-     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
-     *
-     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
-     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
-     * interpolation start/end markers with their escaped counterparts.**
-     *
-     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
-     * output when the $interpolate service processes the text. So, for HTML elements interpolated
-     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
-     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
-     * this is typically useful only when user-data is used in rendering a template from the server, or
-     * when otherwise untrusted data is used by a directive.
-     *
-     * <example>
-     *  <file name="index.html">
-     *    <div ng-init="username='A user'">
-     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
-     *        </p>
-     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
-     *        application, but fails to accomplish their task, because the server has correctly
-     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
-     *        characters.</p>
-     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
-     *        from the database by an administrator.</p>
-     *    </div>
-     *  </file>
-     * </example>
-     *
-     * @param {string} text The text with markup to interpolate.
-     * @param {boolean=} mustHaveExpression if set to true then the interpolation string must have
-     *    embedded expression in order to return an interpolation function. Strings with no
-     *    embedded expression will return null for the interpolation function.
-     * @param {string=} trustedContext when provided, the returned function passes the interpolated

-      * Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
-      * milliseconds.
-      *
-      * The return value of registering an interval function is a promise. This promise will be
-      * notified upon each tick of the interval, and will be resolved after `count` iterations, or
-      * run indefinitely if `count` is not defined. The value of the notification will be the
-      * number of iterations that have run.
-      * To cancel an interval, call `$interval.cancel(promise)`.
-      *
-      * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
-      * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
-      * time.
-      *
-      * <div class="alert alert-warning">
-      * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
-      * with them.  In particular they are not automatically destroyed when a controller's scope or a
-      * directive's element are destroyed.
-      * You should take this into consideration and make sure to always cancel the interval at the
-      * appropriate moment.  See the example below for more details on how and when to do this.
-      * </div>
-      *
-      * @param {function()} fn A function that should be called repeatedly.
-      * @param {number} delay Number of milliseconds between each function call.
-      * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
-      *   indefinitely.
-      * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
-      *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
-      * @param {...*=} Pass additional parameters to the executed function.

-// Sandboxing Angular Expressions
-// ------------------------------
-// Angular expressions are generally considered safe because these expressions only have direct
-// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by
-// obtaining a reference to native JS functions such as the Function constructor.
-//
-// As an example, consider the following Angular expression:
-//
-//   {}.toString.constructor('alert("evil JS code")')
-//
-// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
-// against the expression language, but not to prevent exploits that were enabled by exposing
-// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
-// practice and therefore we are not even trying to protect against interaction with an object
-// explicitly exposed in this way.
-//
-// In general, it is not possible to access a Window object from an angular expression unless a
-// window or some DOM object that has a reference to window is published onto a Scope.
-// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
-// native objects.
-//
-// See https://docs.angularjs.org/guide/security

-/**
- * @ngdoc service
- * @name $q
- * @requires $rootScope
- *
- * @description
- * A service that helps you run functions asynchronously, and use their return values (or exceptions)
- * when they are done processing.
- *
- * This is an implementation of promises/deferred objects inspired by
- * [Kris Kowal's Q](https://github.com/kriskowal/q).
- *
- * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
- * implementations, and the other which resembles ES6 promises to some degree.
- *
- * # $q constructor
- *
- * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
- * function as the first argument. This is similar to the native Promise implementation from ES6 Harmony,
- * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
- *
- * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are
- * available yet.
- *
- * It can be used like so:
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
- *     return $q(function(resolve, reject) {
- *       setTimeout(function() {
- *         if (okToGreet(name)) {
- *           resolve('Hello, ' + name + '!');
- *         } else {
- *           reject('Greeting ' + name + ' is not allowed.');
- *         }
- *       }, 1000);
- *     });
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   });
- * ```
- *
- * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
- *
- * However, the more traditional CommonJS-style usage is still available, and documented below.
- *
- * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
- * interface for interacting with an object that represents the result of an action that is
- * performed asynchronously, and may or may not be finished at any given point in time.
- *
- * From the perspective of dealing with error handling, deferred and promise APIs are to
- * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     var deferred = $q.defer();
- *
- *     setTimeout(function() {
- *       deferred.notify('About to greet ' + name + '.');
- *
- *       if (okToGreet(name)) {
- *         deferred.resolve('Hello, ' + name + '!');
- *       } else {
- *         deferred.reject('Greeting ' + name + ' is not allowed.');
- *       }
- *     }, 1000);
- *
- *     return deferred.promise;
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   }, function(update) {
- *     alert('Got notification: ' + update);
- *   });
- * ```
- *
- * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
- * comes in the way of guarantees that promise and deferred APIs make, see
- * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
- *
- * Additionally the promise api allows for composition that is very hard to do with the
- * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
- * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
- * section on serial or parallel joining of promises.
- *
- * # The Deferred API
- *
- * A new instance of deferred is constructed by calling `$q.defer()`.
- *
- * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
- * that can be used for signaling the successful or unsuccessful completion, as well as the status
- * of the task.
- *
- * **Methods**
- *
- * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
- *   constructed via `$q.reject`, the promise will be rejected instead.
- * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
- *   resolving it with a rejection constructed via `$q.reject`.
- * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
- *   multiple times before the promise is either resolved or rejected.
- *
- * **Properties**
- *
- * - promise – `{Promise}` – promise object associated with this deferred.
- *
- *
- * # The Promise API
- *
- * A new promise instance is created when a deferred instance is created and can be retrieved by
- * calling `deferred.promise`.
- *
- * The purpose of the promise object is to allow for interested parties to get access to the result
- * of the deferred task when it completes.
- *
- * **Methods**
- *
- * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
- *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
- *   as soon as the result is available. The callbacks are called with a single argument: the result
- *   or rejection reason. Additionally, the notify callback may be called zero or more times to
- *   provide a progress indication, before the promise is resolved or rejected.
- *
- *   This method *returns a new promise* which is resolved or rejected via the return value of the
- *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
- *   with the value which is resolved in that promise using
- *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
- *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
- *   resolved or rejected from the notifyCallback method.
- *
- * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
- *
- * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
- *   but to do so without modifying the final value. This is useful to release resources or do some
- *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
- *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
- *   more information.
- *
- * # Chaining promises
- *
- * Because calling the `then` method of a promise returns a new derived promise, it is easily
- * possible to create a chain of promises:
- *
- * ```js
- *   promiseB = promiseA.then(function(result) {
- *     return result + 1;
- *   });
- *
- *   // promiseB will be resolved immediately after promiseA is resolved and its value
- *   // will be the result of promiseA incremented by 1
- * ```
- *
- * It is possible to create chains of any length and since a promise can be resolved with another
- * promise (which will defer its resolution further), it is possible to pause/defer resolution of
- * the promises at any point in the chain. This makes it possible to implement powerful APIs like
- * $http's response interceptors.
- *
- *
- * # Differences between Kris Kowal's Q and $q
- *
- *  There are two main differences:
- *
- * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
- *   mechanism in angular, which means faster propagation of resolution or rejection into your
- *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
- * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
- *   all the important functionality needed for common async tasks.
- *
- *  # Testing
- *
- *  ```js
- *    it('should simulate promise', inject(function($q, $rootScope) {
- *      var deferred = $q.defer();
- *      var promise = deferred.promise;
- *      var resolvedValue;
- *
- *      promise.then(function(value) { resolvedValue = value; });
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Simulate resolving of promise
- *      deferred.resolve(123);
- *      // Note that the 'then' function does not get called synchronously.
- *      // This is because we want the promise API to always be async, whether or not
- *      // it got called synchronously or asynchronously.
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Propagate promise resolution to 'then' functions using $apply().
- *      $rootScope.$apply();
- *      expect(resolvedValue).toEqual(123);
- *    }));
- *  ```
- *
- * @param {function(function, function)} resolver Function which is responsible for resolving or
- *   rejecting the newly created promise. The first parameter is a function which resolves the
- *   promise, the second parameter is a function which rejects the promise.
- *
- * @returns {Promise} The newly created promise.

-/**
- * DESIGN NOTES
- *
- * The design decisions behind the scope are heavily favored for speed and memory consumption.
- *
- * The typical use of scope is to watch the expressions, which most of the time return the same
- * value as last time so we optimize the operation.
- *
- * Closures construction is expensive in terms of speed as well as memory:
- *   - No closures, instead use prototypical inheritance for API
- *   - Internal state needs to be stored on scope directly, which means that private state is
- *     exposed as $$____ properties
- *
- * Loop operations are optimized by using while(count--) { ... }
- *   - this means that in order to keep the same order of execution as addition we have to add
- *     items to the array at the beginning (unshift) instead of at the end (push)
- *
- * Child scopes are created and removed often
- *   - Using an array would be slow since inserts in middle are expensive so we use linked list
- *
- * There are few watches then a lot of observers. This is why you don't want the observer to be
- * implemented in the same way as watch. Watch requires return of initialization function which
- * are expensive to construct.

-     *
-     * @description
-     * A root scope can be retrieved using the {@link ng.$rootScope $rootScope} key from the
-     * {@link auto.$injector $injector}. Child scopes are created using the
-     * {@link ng.$rootScope.Scope#$new $new()} method. (Most scopes are created automatically when
-     * compiled HTML template is executed.) See also the {@link guide/scope Scopes guide} for
-     * an in-depth introduction and usage examples.
-     *
-     *
-     * # Inheritance
-     * A scope can inherit from a parent scope, as in this example:
-     * ```js
-         var parent = $rootScope;
-         var child = parent.$new();
-
-         parent.salutation = "Hello";
-         expect(child.salutation).toEqual('Hello');
-
-         child.salutation = "Welcome";
-         expect(child.salutation).toEqual('Welcome');
-         expect(parent.salutation).toEqual('Hello');
-     * ```
-     *
-     * When interacting with `Scope` in tests, additional helper methods are available on the
-     * instances of `Scope` type. See {@link ngMock.$rootScope.Scope ngMock Scope} for additional
-     * details.

-       * @description
-       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
-       *
-       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
-       *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
-       *   its value when executed multiple times with the same input because it may be executed multiple
-       *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
-       *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).
-       * - The `listener` is called only when the value from the current `watchExpression` and the
-       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
-       *   see below). Inequality is determined according to reference inequality,
-       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
-       *    via the `!==` Javascript operator, unless `objectEquality == true`
-       *   (see next point)
-       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
-       *   according to the {@link angular.equals} function. To save the value of the object for
-       *   later comparison, the {@link angular.copy} function is used. This therefore means that
-       *   watching complex objects will have adverse memory and performance implications.
-       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
-       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
-       *   iteration limit is 10 to prevent an infinite loop deadlock.
-       *
-       *
-       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
-       * you can register a `watchExpression` function with no `listener`. (Be prepared for
-       * multiple calls to your `watchExpression` because it will execute multiple times in a
-       * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
-       *
-       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
-       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
-       * watcher. In rare cases, this is undesirable because the listener is called when the result
-       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
-       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
-       * listener was called due to initialization.
-       *
-       *
-       *
-       * # Example
-       * ```js
-           // let's assume that scope was dependency injected as the $rootScope
-           var scope = $rootScope;
-           scope.name = 'misko';

-             scope.counter = scope.counter + 1;
-           });
-           expect(scope.counter).toEqual(0);
-
-           scope.$digest();
-           // the listener is always called during the first $digest loop after it was registered
-           expect(scope.counter).toEqual(1);

-             function(newValue, oldValue) {
-               if ( newValue !== oldValue ) {
-                 // Only increment the counter if the value changed

-       * @name $rootScope.Scope#$digest
-       * @kind function
-       *
-       * @description
-       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
-       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
-       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
-       * until no more listeners are firing. This means that it is possible to get into an infinite
-       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
-       * iterations exceeds 10.
-       *
-       * Usually, you don't call `$digest()` directly in
-       * {@link ng.directive:ngController controllers} or in
-       * {@link ng.$compileProvider#directive directives}.
-       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
-       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
-       *
-       * If you want to be notified whenever `$digest()` is called,
-       * you can register a `watchExpression` function with
-       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
-       *
-       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
-       *
-       * # Example
-       * ```js
-           var scope = ...;
-           scope.name = 'misko';
-           scope.counter = 0;
-
-           expect(scope.counter).toEqual(0);

- * @description
- *
- * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
- * Contextual Escaping (SCE)} services to AngularJS.
- *
- * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
- * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
- * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
- * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
- * work because `$sce` delegates to `$sceDelegate` for these operations.
- *
- * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
- *
- * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
- * can override it completely to change the behavior of `$sce`, the common case would
- * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
- * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
- * templates.  Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist
- * $sceDelegateProvider.resourceUrlWhitelist} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}

- * **Example**:  Consider the following case. <a name="example"></a>
- *
- * - your app is hosted at url `http://myapp.example.com/`
- * - but some of your templates are hosted on other domains you control such as
- *   `http://srv01.assets.example.com/`,  `http://srv02.assets.example.com/`, etc.
- * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
- *
- * Here is what a secure configuration for this scenario might look like:
- *
- * ```
- *  angular.module('myApp', []).config(function($sceDelegateProvider) {

- * @name $sce
- * @kind function
- *
- * @description
- *
- * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
- *
- * # Strict Contextual Escaping
- *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
- * contexts to result in a value that is marked as safe to use for that context.  One example of
- * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
- * to these contexts as privileged or SCE contexts.
- *
- * As of version 1.2, Angular ships with SCE enabled by default.
- *
- * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow
- * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
- * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
- * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
- * to the top of your HTML document.
- *
- * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
- * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
- *
- * Here's an example of a binding in a privileged context:
- *
- * ```
- * <input ng-model="userHtml" aria-label="User input">
- * <div ng-bind-html="userHtml"></div>
- * ```
- *
- * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
- * disabled, this application allows the user to render arbitrary HTML into the DIV.
- * In a more realistic example, one may be rendering user comments, blog articles, etc. via
- * bindings.  (HTML is just one example of a context where rendering user controlled input creates
- * security vulnerabilities.)
- *
- * For the case of HTML, you might use a library, either on the client side, or on the server side,
- * to sanitize unsafe HTML before binding to the value and rendering it in the document.
- *
- * How would you ensure that every place that used these types of bindings was bound to a value that
- * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
- * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
- * properties/fields and forgot to update the binding to the sanitized value?
- *
- * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
- * determine that something explicitly says it's safe to use a value for binding in that
- * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
- * for those values that you can easily tell are safe - because they were received from your server,
- * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
- * allowing only the files in a specific directory to do this.  Ensuring that the internal API
- * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
- *
- * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
- * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
- * obtain values that will be accepted by SCE / privileged contexts.
- *
- *
- * ## How does it work?
- *
- * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
- * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
- * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
- *
- * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
- * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
- * simplified):
- *
- * ```
- * var ngBindHtmlDirective = ['$sce', function($sce) {
- *   return function(scope, element, attr) {
- *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
- *       element.html(value || '');
- *     });
- *   };
- * }];
- * ```
- *
- * ## Impact on loading templates
- *
- * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
- * `templateUrl`'s specified by {@link guide/directive directives}.
- *
- * By default, Angular only loads templates from the same domain and protocol as the application
- * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
- * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
- * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
- *
- * *Please note*:
- * The browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy apply in addition to this and may further restrict whether the template is successfully
- * loaded.  This means that without the right CORS policy, loading templates from a different domain
- * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
- * browsers.
- *
- * ## This feels like too much overhead
- *
- * It's important to remember that SCE only applies to interpolation expressions.
- *
- * If your expressions are constant literals, they're automatically trusted and you don't need to
- * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
- * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
- *
- * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
- * through {@link ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
- *
- * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
- * templates in `ng-include` from your application's domain without having to even know about SCE.
- * It blocks loading templates from other domains or loading templates over http from an https
- * served document.  You can change these by setting your own custom {@link
- * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
- *
- * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
- * application that's secure and can be audited to verify that with much more ease than bolting
- * security onto an application later.
- *

- * ## What trusted context types are supported?
- *
- * | Context             | Notes          |
- * |---------------------|----------------|
- * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
- * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |

- * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
- *
- *  Each element in these arrays must be one of the following:
- *
- *  - **'self'**
- *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
- *      domain** as the application document using the **same protocol**.
- *  - **String** (except the special value `'self'`)
- *    - The string is matched against the full *normalized / absolute URL* of the resource
- *      being tested (substring matches are not good enough.)
- *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
- *      match themselves.
- *    - `*`: matches zero or more occurrences of any character other than one of the following 6
- *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
- *      in a whitelist.
- *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
- *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
- *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
- *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
- *      http://foo.example.com/templates/**).
- *  - **RegExp** (*see caveat below*)
- *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
- *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
- *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
- *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
- *      small number of cases.  A `.` character in the regex used when matching the scheme or a
- *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
- *      is highly recommended to use the string patterns and only fall back to regular expressions
- *      as a last resort.
- *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
- *      matched against the **entire** *normalized / absolute URL* of the resource being tested
- *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
- *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
- *    - If you are generating your JavaScript from some other templating engine (not
- *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
- *      remember to escape your regular expression (and be aware that you might need more than
- *      one level of escaping depending on your templating engine and the way you interpolated
- *      the value.)  Do make use of your platform's escaping mechanism as it might be good
- *      enough before coding your own.  E.g. Ruby has
- *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
- *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
- *      Javascript lacks a similar built in function for escaping.  Take a look at Google
- *      Closure library's [goog.string.regExpEscape(s)](
- *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).

- * ## Can I disable SCE completely?
- *
- * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
- * for little coding overhead.  It will be much harder to take an SCE disabled application and
- * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
- * for cases where you have a lot of existing code that was written before SCE was introduced and
- * you're migrating them a module at a time.
- *
- * That said, here's how you can completely disable SCE:
- *
- * ```
- * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
- *   // Completely disable SCE.  For demonstration purposes only!
- *   // Do not use in new projects.
- *   $sceProvider.enabled(false);
- * });
- * ```

-  /* Design notes on the default implementation for SCE.
-   *
-   * The API contract for the SCE delegate
-   * -------------------------------------
-   * The SCE delegate object must provide the following 3 methods:
-   *
-   * - trustAs(contextEnum, value)
-   *     This method is used to tell the SCE service that the provided value is OK to use in the
-   *     contexts specified by contextEnum.  It must return an object that will be accepted by
-   *     getTrusted() for a compatible contextEnum and return this value.
-   *
-   * - valueOf(value)
-   *     For values that were not produced by trustAs(), return them as is.  For values that were
-   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
-   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
-   *     such a value.
-   *
-   * - getTrusted(contextEnum, value)
-   *     This function should return the a value that is safe to use in the context specified by
-   *     contextEnum or throw and exception otherwise.
-   *
-   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
-   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
-   * instance, an implementation could maintain a registry of all trusted objects by context.  In
-   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
-   * return the same object passed in if it was found in the registry under a compatible context or
-   * throw an exception otherwise.  An implementation might only wrap values some of the time based
-   * on some criteria.  getTrusted() might return a value and not throw an exception for special
-   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
-   *
-   *
-   * A note on the inheritance model for SCE contexts
-   * ------------------------------------------------
-   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
-   * is purely an implementation details.
-   *
-   * The contract is simply this:
-   *
-   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
-   *     will also succeed.
-   *
-   * Inheritance happens to capture this in a natural way.  In some future, we
-   * may not use inheritance anymore.  That is OK because no code outside of
-   * sce.js and sceSpecs.js would need to be aware of this detail.

- *
- * Implementation Notes for non-IE browsers
- * ----------------------------------------
- * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
- * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
- * URL will be resolved into an absolute URL in the context of the application document.
- * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
- * properties are all populated to reflect the normalized URL.  This approach has wide
- * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
- * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
- *
- * Implementation Notes for IE
- * ---------------------------
- * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
- * browsers.  However, the parsed components will not be set if the URL assigned did not specify
- * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
- * work around that by performing the parsing in a 2nd step by taking a previously normalized
- * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
- * properties such as protocol, hostname, port, etc.

- *
- * <div class="alert alert-warning">
- * **Note:** Filter names must be valid angular {@link expression} identifiers, such as `uppercase` or `orderBy`.
- * Names with special characters, such as hyphens and dots, are not allowed. If you wish to namespace

- * (`myapp_subsection_filterx`).
- * </div>
- *
- * ```js
- *   // Filter registration
- *   function MyModule($provide, $filterProvider) {

- *     $provide.value('greet', function(name){

- *         return text && greet(text) || text;

- *     });
- *   }

- *
- * The filter function is registered with the `$injector` under the filter name suffix with
- * `Filter`.
- *
- * ```js
- *   it('should be the same instance', inject(

-/**
- * @ngdoc filter
- * @name filter
- * @kind function
- *
- * @description
- * Selects a subset of items from `array` and returns it as a new array.
- *
- * @param {Array} array The source array.
- * @param {string|Object|function()} expression The predicate to be used for selecting items from
- *   `array`.
- *
- *   Can be one of:
- *
- *   - `string`: The string is used for matching against the contents of the `array`. All strings or
- *     objects with string properties in `array` that match this string will be returned. This also
- *     applies to nested object properties.
- *     The predicate can be negated by prefixing the string with `!`.
- *
- *   - `Object`: A pattern object can be used to filter specific properties on objects contained
- *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
- *     which have property `name` containing "M" and property `phone` containing "1". A special
- *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
- *     property of the object or its nested object properties. That's equivalent to the simple
- *     substring match with a `string` as described above. The predicate can be negated by prefixing
- *     the string with `!`.
- *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
- *     not containing "M".
- *
- *     Note that a named property will match properties on the same level only, while the special
- *     `$` property will match properties on the same level or deeper. E.g. an array item like
- *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
- *     **will** be matched by `{$: 'John'}`.
- *
- *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
- *     The function is called for each element of the array, with the element, its index, and
- *     the entire array itself as arguments.
- *
- *     The final result is an array of those elements that the predicate returned true for.
- *
- * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
- *     determining if the expected value (from the filter expression) and actual value (from
- *     the object in the array) should be considered a match.
- *
- *   Can be one of:
- *
- *   - `function(actual, expected)`:
- *     The function will be given the object value and the predicate value to compare and
- *     should return true if both values should be considered equal.
- *
- *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
- *     This is essentially strict comparison of expected and actual.
- *
- *   - `false|undefined`: A short hand for a function which will look for a substring match in case
- *     insensitive way.
- *
- *     Primitive values are converted to strings. Objects are not compared against primitives,
- *     unless they have a custom `toString` method (e.g. `Date` objects).
- *

- * @description
- * Formats a number as text.
- *
- * If the input is null or undefined, it will just be returned.
- * If the input is infinite (Infinity/-Infinity) the Infinity symbol '∞' is returned.
- * If the input is not a number an empty string is returned.
- *
- *
- * @param {number|string} number Number to format.
- * @param {(number|string)=} fractionSize Number of decimal places to round the number to.
- * If this is not provided then the fraction size is computed from the current locale's number
- * formatting pattern. In the case of the default locale, it will be 3.
- * @returns {string} Number rounded to decimalPlaces and places a “,” after each third digit.

-/**
- * @ngdoc filter
- * @name date
- * @kind function
- *
- * @description
- *   Formats `date` to a string based on the requested `format`.
- *
- *   `format` string can be composed of the following elements:
- *
- *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
- *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
- *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
- *   * `'MMMM'`: Month in year (January-December)
- *   * `'MMM'`: Month in year (Jan-Dec)
- *   * `'MM'`: Month in year, padded (01-12)
- *   * `'M'`: Month in year (1-12)
- *   * `'dd'`: Day in month, padded (01-31)
- *   * `'d'`: Day in month (1-31)
- *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
- *   * `'EEE'`: Day in Week, (Sun-Sat)
- *   * `'HH'`: Hour in day, padded (00-23)
- *   * `'H'`: Hour in day (0-23)
- *   * `'hh'`: Hour in AM/PM, padded (01-12)
- *   * `'h'`: Hour in AM/PM, (1-12)
- *   * `'mm'`: Minute in hour, padded (00-59)
- *   * `'m'`: Minute in hour (0-59)
- *   * `'ss'`: Second in minute, padded (00-59)
- *   * `'s'`: Second in minute (0-59)
- *   * `'sss'`: Millisecond in second, padded (000-999)
- *   * `'a'`: AM/PM marker
- *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
- *   * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
- *   * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
- *   * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
- *   * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
- *
- *   `format` string can also be one of the following predefined
- *   {@link guide/i18n localizable formats}:
- *
- *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
- *     (e.g. Sep 3, 2010 12:05:08 PM)
- *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 PM)
- *   * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US  locale
- *     (e.g. Friday, September 3, 2010)
- *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
- *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
- *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
- *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
- *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
- *
- *   `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
- *   `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
- *   (e.g. `"h 'o''clock'"`).
- *
- * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
- *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
- *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
- *    specified in the string input, the time is considered to be in the local timezone.
- * @param {string=} format Formatting rules (see Description). If not specified,
- *    `mediumDate` is used.
- * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
- *    continental US time zone abbreviations, but for general use, use a time zone offset, for
- *    example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *    If not specified, the timezone of the browser will be used.
- * @returns {string} Formatted string or the input if input is not recognized as date/millis.

- * @ngdoc filter
- * @name limitTo
- * @kind function
- *
- * @description
- * Creates a new array or string containing only a specified number of elements. The elements
- * are taken from either the beginning or the end of the source array, string or number, as specified by
- * the value and sign (positive or negative) of `limit`. If a number is used as input, it is
- * converted to a string.
- *
- * @param {Array|string|number} input Source array, string or number to be limited.
- * @param {string|number} limit The length of the returned array or string. If the `limit` number
- *     is positive, `limit` number of items from the beginning of the source array/string are copied.
- *     If the number is negative, `limit` number  of items from the end of the source array/string
- *     are copied. The `limit` will be trimmed if it exceeds `array.length`. If `limit` is undefined,
- *     the input will be returned unchanged.
- * @param {(string|number)=} begin Index at which to begin limitation. As a negative index, `begin`
- *     indicates an offset from the end of `input`. Defaults to `0`.
- * @returns {Array|string} A new sub-array or substring of length `limit` or less if input array
- *     had less than `limit` elements.

-/**
- * @ngdoc filter
- * @name orderBy
- * @kind function
- *
- * @description
- * Orders a specified `array` by the `expression` predicate. It is ordered alphabetically
- * for strings and numerically for numbers. Note: if you notice numbers are not being sorted
- * as expected, make sure they are actually being saved as numbers and not strings.
- *
- * @param {Array} array The array to sort.
- * @param {function(*)|string|Array.<(function(*)|string)>=} expression A predicate to be
- *    used by the comparator to determine the order of elements.
- *
- *    Can be one of:
- *
- *    - `function`: Getter function. The result of this function will be sorted using the
- *      `<`, `===`, `>` operator.
- *    - `string`: An Angular expression. The result of this expression is used to compare elements
- *      (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by
- *      3 first characters of a property called `name`). The result of a constant expression
- *      is interpreted as a property name to be used in comparisons (for example `"special name"`
- *      to sort object by the value of their `special name` property). An expression can be
- *      optionally prefixed with `+` or `-` to control ascending or descending sort order
- *      (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array
- *      element itself is used to compare where sorting.
- *    - `Array`: An array of function or string predicates. The first predicate in the array
- *      is used for sorting, but when two items are equivalent, the next predicate is used.
- *
- *    If the predicate is missing or empty then it defaults to `'+'`.
- *
- * @param {boolean=} reverse Reverse the order of the array.
- * @returns {Array} Sorted copy of the source array.
- *
- *
- * @example
- * The example below demonstrates a simple ngRepeat, where the data is sorted
- * by age in descending order (predicate is set to `'-age'`).
- * `reverse` is not set, which means it defaults to `false`.

- * @ngdoc directive
- * @name ngHref
- * @restrict A
- * @priority 99
- *
- * @description
- * Using Angular markup like `{{hash}}` in an href attribute will
- * make the link go to the wrong URL if the user clicks it before
- * Angular has a chance to replace the `{{hash}}` markup with its
- * value. Until Angular replaces the markup the link will be broken
- * and will most likely return a 404 error. The `ngHref` directive
- * solves this problem.
- *
- * The wrong way to write it:
- * ```html
- * <a href="http://www.gravatar.com/avatar/{{hash}}">link1</a>
- * ```
- *
- * The correct way to write it:
- * ```html

-/**
- * @ngdoc directive
- * @name ngDisabled
- * @restrict A
- * @priority 100
- *
- * @description
- *
- * This directive sets the `disabled` attribute on the element if the
- * {@link guide/expression expression} inside `ngDisabled` evaluates to truthy.
- *
- * A special directive is necessary because we cannot use interpolation inside the `disabled`
- * attribute.  The following example would make the button enabled on Chrome/Firefox
- * but not on older IEs:
- *
- * ```html
- * <!-- See below for an example of ng-disabled being used correctly -->
- * <div ng-init="isDisabled = false">
- *  <button disabled="{{isDisabled}}">Disabled</button>
- * </div>
- * ```
- *
- * This is because the HTML specification does not require browsers to preserve the values of
- * boolean attributes such as `disabled` (Their presence means true and their absence means false.)
- * If we put an Angular interpolation expression into such an attribute then the
- * binding information would be lost when the browser removes the attribute.
- *
- * @example
-    <example>
-      <file name="index.html">
-        <label>Click me to toggle: <input type="checkbox" ng-model="checked"></label><br/>

- /**
- * @ngdoc directive
- * @name form
- * @restrict E
- *
- * @description
- * Directive that instantiates
- * {@link form.FormController FormController}.
- *
- * If the `name` attribute is specified, the form controller is published onto the current scope under
- * this name.
- *
- * # Alias: {@link ng.directive:ngForm `ngForm`}
- *
- * In Angular, forms can be nested. This means that the outer form is valid when all of the child
- * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
- * Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to
- * `<form>` but can be nested.  This allows you to have nested forms, which is very useful when
- * using Angular validation directives in forms that are dynamically generated using the
- * {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name`
- * attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an
- * `ngForm` directive and nest these in an outer `form` element.
- *
- *
- * # CSS classes
- *  - `ng-valid` is set if the form is valid.
- *  - `ng-invalid` is set if the form is invalid.
- *  - `ng-pending` is set if the form is pending.
- *  - `ng-pristine` is set if the form is pristine.
- *  - `ng-dirty` is set if the form is dirty.
- *  - `ng-submitted` is set if the form was submitted.
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- *
- * # Submitting a form and preventing the default action
- *
- * Since the role of forms in client-side Angular applications is different than in classical
- * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
- * page reload that sends the data to the server. Instead some javascript logic should be triggered
- * to handle the form submission in an application-specific way.
- *
- * For this reason, Angular prevents the default action (form submission to the server) unless the
- * `<form>` element has an `action` attribute specified.
- *
- * You can use one of the following two ways to specify what javascript method should be called when
- * a form is submitted:
- *
- * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
- * - {@link ng.directive:ngClick ngClick} directive on the first
-  *  button or input field of type submit (input[type=submit])
- *
- * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
- * or {@link ng.directive:ngClick ngClick} directives.
- * This is because of the following form submission rules in the HTML specification:
- *
- * - If a form has only one input field then hitting enter in this field triggers form submit
- * (`ngSubmit`)
- * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
- * doesn't trigger submit
- * - if a form has one or more input fields and one or more buttons or input[type=submit] then
- * hitting enter in any of the input fields will trigger the click handler on the *first* button or
- * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
- *
- * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
- * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * ## Animation Hooks
- *
- * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
- * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
- * other validations that are performed within the form. Animations in ngForm are similar to how
- * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
- * as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style a form element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-form {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-form.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
-    <example deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
-      <file name="index.html">
-       <script>
-         angular.module('formExample', [])

-        .my-form {

-          background: transparent;
-        }
-        .my-form.ng-invalid {
-          background: red;
-        }
-       </style>
-       <form name="myForm" ng-controller="FormController" class="my-form">

-   * @name input[text]
-   *
-   * @description
-   * Standard HTML text input with angular data binding, inherited by most of the `input` elements.
-   *
-   *
-   * @param {string} ngModel Assignable angular expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} required Adds `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel value does not match
-   *    a RegExp found by evaluating the Angular expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.<br />
-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
-   *    start at the index of the last search's match, thus not taking the whole input value into
-   *    account.
-   * @param {string=} ngChange Angular expression to be executed when input changes due to user
-   *    interaction with the input element.
-   * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
-   *    This parameter is ignored for input[type=password] controls, which will never trim the
-   *    input.

-     * @description
-     * Input with date validation and transformation. In browsers that do not yet support
-     * the HTML5 date input, a text element will be used. In that case, text must be entered in a valid ISO-8601
-     * date format (yyyy-MM-dd), for example: `2009-01-06`. Since many
-     * modern browsers do not yet support this input type, it is important to provide cues to users on the
-     * expected input format via a placeholder or label.
-     *
-     * The model must always be a Date object, otherwise Angular will throw an error.
-     * Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string.
-     *
-     * The timezone to be used to read/write the `Date` instance in the model can be defined using
-     * {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser.
-     *
-     * @param {string} ngModel Assignable angular expression to data-bind to.
-     * @param {string=} name Property name of the form under which the control is published.
-     * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`. This must be a
-     *   valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
-     *   (e.g. `min="{{minDate | date:'yyyy-MM-dd'}}"`). Note that `min` will also add native HTML5
-     *   constraint validation.
-     * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`. This must be
-     *   a valid ISO date string (yyyy-MM-dd). You can also use interpolation inside this attribute
-     *   (e.g. `max="{{maxDate | date:'yyyy-MM-dd'}}"`). Note that `max` will also add native HTML5
-     *   constraint validation.
-     * @param {(date|string)=} ngMin Sets the `min` validation constraint to the Date / ISO date string
-     *   the `ngMin` expression evaluates to. Note that it does not set the `min` attribute.
-     * @param {(date|string)=} ngMax Sets the `max` validation constraint to the Date / ISO date string
-     *   the `ngMax` expression evaluates to. Note that it does not set the `max` attribute.
-     * @param {string=} required Sets `required` validation error key if the value is not entered.
-     * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-     *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-     *    `required` when you want to data-bind to the `required` attribute.

-   *   This must be a valid ISO month format (yyyy-MM). You can also use interpolation inside this

-   *
-   * In browsers that follow the

-   * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
-   * If a non-number is entered in the input, the browser will report the value as an empty string,
-   * which means the view / model values in `ngModel` and subsequently the scope value
-   * will also be an empty string.
-   *
-   *
-   * @param {string} ngModel Assignable angular expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
-   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
-   * @param {string=} required Sets `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel value does not match
-   *    a RegExp found by evaluating the Angular expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.<br />
-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to

-   *    a RegExp found by evaluating the Angular expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.<br />
-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
-   *    start at the index of the last search's match, thus not taking the whole input value into
-   *    account.
-   * @param {string=} ngChange Angular expression to be executed when input changes due to user
-   *    interaction with the input element.

- * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element

- *
- * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like

- *
- * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
- * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
- * element attribute, it makes the bindings invisible to the user while the page is loading.

- * An alternative solution to this problem would be using the

- * the resulting HTML content will be sanitized using the {@link ngSanitize.$sanitize $sanitize} service.
- * To utilize this functionality, ensure that `$sanitize` is available, for example, by including {@link
- * ngSanitize} in your module's dependencies (not in core Angular). In order to use {@link ngSanitize}
- * in your module's dependencies, you need to include "angular-sanitize.js" in your application.
- *
- * You may also bypass sanitization for values you know are safe. To do so, bind to
- * an explicitly trusted value via {@link ng.$sce#trustAsHtml $sce.trustAsHtml}.  See the example
- * under {@link ng.$sce#show-me-an-example-using-sce- Strict Contextual Escaping (SCE)}.
- *
- * Note: If a `$sanitize` service is unavailable and the bound value isn't explicitly trusted, you
- * will have an exception (instead of an exploit.)

- * @param {expression} ngBindHtml {@link guide/expression Expression} to evaluate.

- * Evaluate the given expression when the user changes the input.
- * The expression is evaluated immediately, unlike the JavaScript onchange event
- * which only triggers at the end of a change (usually, when the user leaves the

- *
- * The `ngChange` expression is only evaluated when a change in the input value causes
- * a new value to be committed to the model.
- *
- * It will not be evaluated:
- * * if the value returned from the `$parsers` transformation pipeline has not changed
- * * if the input has continued to be invalid since the model will stay `null`
- * * if the model is changed programmatically and not by a change to the input value

-/**
- * @ngdoc directive
- * @name ngClass
- * @restrict AC
- *
- * @description
- * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
- * an expression that represents all classes to be added.
- *
- * The directive operates in three different ways, depending on which of three types the expression
- * evaluates to:
- *
- * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
- * names.
- *
- * 2. If the expression evaluates to an object, then for each key-value pair of the
- * object with a truthy value the corresponding key is used as a class name.
- *
- * 3. If the expression evaluates to an array, each element of the array should either be a string as in
- * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
- * to give you more control over what CSS classes appear. See the code below for an example of this.
- *
- *
- * The directive won't add duplicate classes if a particular class was already set.
- *
- * When the expression changes, the previously added classes are removed and only then are the
- * new classes added.
- *
- * @animations
- * **add** - happens just before the class is applied to the elements
- *
- * **remove** - happens just before the class is removed from the element
- *
- * @element ANY
- * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
- *   of the evaluation can be a string representing space delimited class
- *   names, an array, or a map of class names to boolean values. In the case of a map, the
- *   names of the properties whose values are truthy will be added as css classes to the
- *   element.
- *
- * @example Example that demonstrates basic bindings via ngClass directive.

-       }
-
-       .base-class.my-class {
-         color: red;
-         font-size:3em;

-     <file name="protractor.js" type="protractor">
-       it('should check ng-class', function() {
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-
-         element(by.id('setbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).
-           toMatch(/my-class/);

-           toMatch(/my-class/);
-       });
-     </file>
-   </example>
-
-
-   ## ngClass and pre-existing CSS3 Transitions/Animations
-   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
-   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
-   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
-   to view the step by step details of {@link $animate#addClass $animate.addClass} and
-   {@link $animate#removeClass $animate.removeClass}.

-/**
- * @ngdoc directive
- * @name ngCloak
- * @restrict AC
- *
- * @description
- * The `ngCloak` directive is used to prevent the Angular html template from being briefly
- * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
- * directive to avoid the undesirable flicker effect caused by the html template display.
- *
- * The directive can be applied to the `<body>` element, but the preferred usage is to apply
- * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
- * of the browser view.
- *
- * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
- * `angular.min.js`.
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```css
- * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
- *   display: none !important;
- * }
- * ```
- *
- * When this css rule is loaded by the browser, all html elements (including their children) that
- * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
- * during the compilation of the template it deletes the `ngCloak` element attribute, making
- * the compiled element visible.
- *
- * For the best result, the `angular.js` script must be loaded in the head section of the html
- * document; alternatively, the css rule above must be included in the external stylesheet of the
- * application.
- *
- * @element ANY
- *
- * @example
-   <example>
-     <file name="index.html">
-        <div id="template1" ng-cloak>{{ 'hello' }}</div>
-        <div id="template2" class="ng-cloak">{{ 'world' }}</div>

-/**
- * @ngdoc directive
- * @name ngController
- *
- * @description
- * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
- * supports the principles behind the Model-View-Controller design pattern.
- *
- * MVC components in angular:
- *
- * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
- *   are accessed through bindings.
- * * View — The template (HTML with data bindings) that is rendered into the View.
- * * Controller — The `ngController` directive specifies a Controller class; the class contains business
- *   logic behind the application to decorate the scope with functions and values
- *
- * Note that you can also attach controllers to the DOM by declaring it in a route definition
- * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
- * again using `ng-controller` in the template itself.  This will cause the controller to be attached
- * and executed twice.
- *
- * @element ANY
- * @scope
- * @priority 500
- * @param {expression} ngController Name of a constructor function registered with the current
- * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
- * that on the current scope evaluates to a constructor function.
- *
- * The controller instance can be published into a scope property by specifying
- * `ng-controller="as propertyName"`.
- *
- * If the current `$controllerProvider` is configured to use globals (via
- * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
- * also be the name of a globally accessible constructor function (not recommended).
- *
- * @example
- * Here is a simple form for editing user contact information. Adding, removing, clearing, and
- * greeting are methods declared on the controller (see source tab). These methods can
- * easily be called from the angular markup. Any changes to the data are automatically reflected
- * in the View without the need for a manual update.
- *
- * Two different declaration styles are included below:
- *
- * * one binds methods and properties directly onto the controller using `this`:
- * `ng-controller="SettingsController1 as settings"`
- * * one injects `$scope` into the controller:
- * `ng-controller="SettingsController2"`
- *
- * The second option is more common in the Angular community, and is generally used in boilerplates
- * and in this guide. However, there are advantages to binding properties directly to the controller
- * and avoiding scope.
- *
- * * Using `controller as` makes it obvious which controller you are accessing in the template when
- * multiple controllers apply to an element.
- * * If you are writing your controllers as classes you have easier access to the properties and
- * methods, which will appear on the scope, from inside the controller code.
- * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
- * inheritance masking primitives.
- *
- * This example demonstrates the `controller as` syntax.

- * <example name="ngControllerAs" module="controllerAsExample">
- *   <file name="index.html">
- *    <div id="ctrl-as-exmpl" ng-controller="SettingsController1 as settings">

-/**
- * @ngdoc directive
- * @name ngCsp
- *
- * @element html
- * @description
- *
- * Angular has some features that can break certain
- * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
- *
- * If you intend to implement these rules then you must tell Angular not to use these features.
- *
- * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
- *
- *
- * The following rules affect Angular:
- *
- * * `unsafe-eval`: this rule forbids apps to use `eval` or `Function(string)` generated functions
- * (among other things). Angular makes use of this in the {@link $parse} service to provide a 30%
- * increase in the speed of evaluating Angular expressions.
- *
- * * `unsafe-inline`: this rule forbids apps from inject custom styles into the document. Angular
- * makes use of this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}).
- * To make these directives work when a CSP rule is blocking inline styles, you must link to the
- * `angular-csp.css` in your HTML manually.
- *
- * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking unsafe-eval
- * and automatically deactivates this feature in the {@link $parse} service. This autodetection,
- * however, triggers a CSP error to be logged in the console:
- *
- * ```
- * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
- * script in the following Content Security Policy directive: "default-src 'self'". Note that
- * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
- * ```
- *
- * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
- * directive on an element of the HTML document that appears before the `<script>` tag that loads
- * the `angular.js` file.
- *
- * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
- *
- * You can specify which of the CSP related Angular features should be deactivated by providing
- * a value for the `ng-csp` attribute. The options are as follows:
- *
- * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
- *
- * * no-unsafe-eval: this stops Angular from optimising $parse with unsafe eval of strings
- *
- * You can use these values in the following combinations:
- *
- *
- * * No declaration means that Angular will assume that you can do inline styles, but it will do
- * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous versions
- * of Angular.
- *
- * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
- * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous versions
- * of Angular.
- *
- * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can inject
- * inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
- *
- * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
- * run eval - no automcatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
- *
- * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
- * styles nor use eval, which is the same as an empty: ng-csp.
- * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
- *
- * @example
- * This example shows how to apply the `ngCsp` directive to the `html` tag.
-   ```html
-     <!doctype html>
-     <html ng-app ng-csp>
-     ...
-     ...
-     </html>
-   ```
-  * @example

-      // csp mode in our http server!

-/**
- * @ngdoc directive
- * @name ngIf
- * @restrict A
- * @multiElement
- *
- * @description
- * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
- * {expression}. If the expression assigned to `ngIf` evaluates to a false
- * value then the element is removed from the DOM, otherwise a clone of the
- * element is reinserted into the DOM.
- *
- * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
- * element in the DOM rather than changing its visibility via the `display` css property.  A common
- * case when this difference is significant is when using css selectors that rely on an element's
- * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
- *
- * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
- * is created when the element is restored.  The scope created within `ngIf` inherits from
- * its parent scope using
- * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
- * An important implication of this is if `ngModel` is used within `ngIf` to bind to
- * a javascript primitive defined in the parent scope. In this case any modifications made to the
- * variable within the child scope will override (hide) the value in the parent scope.
- *
- * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
- * is if an element's class attribute is directly modified after it's compiled, using something like
- * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
- * the added class will be lost because the original compiled state is used to regenerate the element.
- *
- * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
- * and `leave` effects.
- *
- * @animations
- * enter - happens just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container
- * leave - happens just before the `ngIf` contents are removed from the DOM
- *
- * @element ANY
- * @scope
- * @priority 600
- * @param {expression} ngIf If the {@link guide/expression expression} is falsy then

- * The `ngInit` directive allows you to evaluate an expression in the
- * current scope.
- *
- * <div class="alert alert-danger">
- * This directive can be abused to add unnecessary amounts of logic into your templates.
- * There are only a few appropriate uses of `ngInit`, such as for aliasing special properties of
- * {@link ng.directive:ngRepeat `ngRepeat`}, as seen in the demo below; and for injecting data via
- * server side scripting. Besides these few cases, you should use {@link guide/controller controllers}
- * rather than `ngInit` to initialize values on a scope.
- * </div>
- *
- * <div class="alert alert-warning">
- * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make
- * sure you have parentheses to ensure correct operator precedence:
- * <pre class="prettyprint">
- * `<div ng-init="test1 = ($index | toString)"></div>`
- * </pre>
- * </div>
- *
- * @priority 450
- *
- * @element ANY
- * @param {expression} ngInit {@link guide/expression Expression} to eval.

-/**
- * @ngdoc directive
- * @name ngList
- *
- * @description
- * Text input that converts between a delimited string and an array of strings. The default
- * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
- * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
- *
- * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
- * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
- *   list item is respected. This implies that the user of the directive is responsible for
- *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
- *   tab or newline character.
- * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
- *   when joining the list items back together) and whitespace around each list item is stripped
- *   before it is added to the model.

- * @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to

- *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
- *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
- *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
- *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
- *      will only run once all synchronous validators have passed.
- *
- * Please note that if $http is used then it is important that the server returns a success HTTP response code
- * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
- *
- * ```js
- * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *
- *   // Lookup user by username
- *   return $http.get('/api/users/' + value).

- *
- * @property {Array.<Function>} $viewChangeListeners Array of functions to execute whenever the
- *     view value has changed. It is called with no arguments, and its return value is ignored.
- *     This can be used in place of additional $watches against the model value.
- *
- * @property {Object} $error An object hash with all failing validator ids as keys.
- * @property {Object} $pending An object hash with all pending validator ids as keys.
- *
- * @property {boolean} $untouched True if control has not lost focus yet.

- * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
- * The controller contains services for data-binding, validation, CSS updates, and value formatting
- * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
- * listening to DOM events.
- * Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding to control elements.
- * Angular provides this DOM logic for most {@link input `input`} elements.
- * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
- * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
- *
- * @example
- * ### Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.
- *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
- * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
- * that content using the `$sce` service.
- *
- * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
-    <file name="style.css">
-      [contenteditable] {
-        border: 1px solid black;

-   * @description
-   * Update the view value.
-   *
-   * This method should be called when a control wants to change the view value; typically,
-   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
-   * directive calls it when the value of the input changes and {@link ng.directive:select select}
-   * calls it when an option is selected.
-   *
-   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
-   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
-   * value sent directly for processing, finally to be applied to `$modelValue` and then the
-   * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
-   * in the `$viewChangeListeners` list, are called.
-   *
-   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
-   * and the `default` trigger is not listed, all those actions will remain pending until one of the
-   * `updateOn` events is triggered on the DOM element.
-   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
-   * directive is used with a custom debounce for this particular event.
-   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
-   * is specified, once the timer runs out.
-   *
-   * When used with standard inputs, the view value will always be a string (which is in some cases
-   * parsed into another type, such as a `Date` object for `input[date]`.)
-   * However, custom controls might also pass objects to this method. In this case, we should make
-   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
-   * perform a deep watch of objects, it only looks for a change of identity. If you only change
-   * the property of the object then ngModel will not realise that the object has changed and
-   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
-   * not change properties of the copy once it has been passed to `$setViewValue`.
-   * Otherwise you may cause the model value on the scope to change incorrectly.
-   *
-   * <div class="alert alert-info">
-   * In any case, the value passed to the method should always reflect the current value
-   * of the control. For example, if you are calling `$setViewValue` for an input element,
-   * you should pass the input DOM value. Otherwise, the control and the scope model become
-   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
-   * the control's DOM value in any way. If we want to change the control's DOM value
-   * programmatically, we should update the `ngModel` scope expression. Its new value will be
-   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
-   * to update the DOM, and finally call `$validate` on it.

-/**
- * @ngdoc directive
- * @name ngModel
- *
- * @element input
- * @priority 1
- *
- * @description
- * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
- * property on the scope using {@link ngModel.NgModelController NgModelController},
- * which is created and exposed by this directive.
- *
- * `ngModel` is responsible for:
- *
- * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
- *   require.
- * - Providing validation behavior (i.e. required, number, email, url).
- * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`, `ng-untouched`) including animations.
- * - Registering the control with its parent {@link ng.directive:form form}.
- *
- * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
- * current scope. If the property doesn't already exist on this scope, it will be created
- * implicitly and added to the scope.
- *
- * For best practices on using `ngModel`, see:
- *
- *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
- *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - {@link ng.directive:input input}
- *    - {@link input[text] text}
- *    - {@link input[checkbox] checkbox}
- *    - {@link input[radio] radio}
- *    - {@link input[number] number}
- *    - {@link input[email] email}
- *    - {@link input[url] url}
- *    - {@link input[date] date}
- *    - {@link input[datetime-local] datetime-local}
- *    - {@link input[time] time}
- *    - {@link input[month] month}
- *    - {@link input[week] week}
- *  - {@link ng.directive:select select}
- *  - {@link ng.directive:textarea textarea}
- *
- * # CSS classes
- * The following CSS classes are added and removed on the associated input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid`: the model is valid
- *  - `ng-invalid`: the model is invalid
- *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
- *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
- *  - `ng-pristine`: the control hasn't been interacted with yet
- *  - `ng-dirty`: the control has been interacted with
- *  - `ng-touched`: the control has been blurred
- *  - `ng-untouched`: the control hasn't been blurred
- *  - `ng-pending`: any `$asyncValidators` are unfulfilled
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- * ## Animation Hooks
- *
- * Animations within models are triggered when any of the associated CSS classes are added and removed
- * on the input element which is attached to the model. These classes are: `.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
- * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample">
-     <file name="index.html">
-       <script>
-        angular.module('inputExample', [])
-          .controller('ExampleController', ['$scope', function($scope) {
-            $scope.val = '1';
-          }]);
-       </script>
-       <style>
-         .my-input {
-           transition:all linear 0.5s;
-           background: transparent;
-         }
-         .my-input.ng-invalid {
-           color:white;
-           background: red;
-         }
-       </style>
-       <p id="inputDescription">
-        Update input to see transitions when valid/invalid.
-        Integer is a valid value.
-       </p>
-       <form name="testForm" ng-controller="ExampleController">
-         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
-                aria-describedby="inputDescription" />
-       </form>
-     </file>
- * </example>
- *
- * ## Binding to a getter/setter
- *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
- * function that returns a representation of the model when called with zero arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes useful to use this
- * for models that have an internal representation that's different from what the model exposes
- * to the view.
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
- * frequently than other parts of your code.
- * </div>
- *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
- * a `<form>`, which will enable this behavior for all `<input>`s within it. See
- * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
- *
- * The following example shows how to use `ngModel` with a getter/setter:
- *
- * @example
- * <example name="ngModel-getter-setter" module="getterSetterExample">
-     <file name="index.html">
-       <div ng-controller="ExampleController">
-         <form name="userForm">
-           <label>Name:
-             <input type="text" name="userName"
-                    ng-model="user.name"
-                    ng-model-options="{ getterSetter: true }" />
-           </label>
-         </form>
-         <pre>user.name = <span ng-bind="user.name()"></span></pre>
-       </div>
-     </file>
-     <file name="app.js">
-       angular.module('getterSetterExample', [])
-         .controller('ExampleController', ['$scope', function($scope) {
-           var _name = 'Brian';
-           $scope.user = {
-             name: function(newName) {
-              // Note that newName can be undefined for two reasons:
-              // 1. Because it is called as a getter and thus called with no arguments
-              // 2. Because the property should actually be set to undefined. This happens e.g. if the
-              //    input is invalid
-              return arguments.length ? (_name = newName) : _name;
-             }
-           };

-/**
- * @ngdoc directive
- * @name ngModelOptions
- *
- * @description
- * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
- * events that will trigger a model update and/or a debouncing delay so that the actual update only
- * takes place when a timer expires; this timer will be reset after another change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
- * be different from the value in the actual model. This means that if you update the model you
- * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced action is canceled.
- *
- * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
- * method is by making sure the input is placed inside a form that has a `name` attribute. This is
- * important because `form` controllers are published to the related scope under the name in their
- * `name` attribute.
- *
- * Any pending changes will take place immediately when an enclosing form is submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * `ngModelOptions` has an effect on the element it's declared on and its descendants.
- *
- * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
- *   - `updateOn`: string specifying which event should the input be bound to. You can set several
- *     events using an space delimited list. There is a special event called `default` that
- *     matches the default events belonging of the control.
- *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
- *     custom value for each event. For example:
- *     `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"`
- *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
- *     not validate correctly instead of the default behavior of setting the model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
-       `ngModel` as getters/setters.
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
- *     `<input type="date">`, `<input type="time">`, ... . It understands UTC/GMT and the
- *     continental US time zone abbreviations, but for general use, use a time zone offset, for
- *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *     If not specified, the timezone of the browser will be used.

-/**
- * @ngdoc directive
- * @name ngOptions
- * @restrict A
- *
- * @description
- *
- * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
- * elements for the `<select>` element using the array or object obtained by evaluating the
- * `ngOptions` comprehension expression.
- *
- * In many cases, `ngRepeat` can be used on `<option>` elements instead of `ngOptions` to achieve a
- * similar result. However, `ngOptions` provides some benefits such as reducing memory and
- * increasing speed by not creating a new scope for each repeated instance, as well as providing
- * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
- * comprehension expression. `ngOptions` should be used when the `<select>` model needs to be bound
- *  to a non-string value. This is because an option element can only be bound to string values at
- * present.
- *
- * When an item in the `<select>` menu is selected, the array element or object property
- * represented by the selected option will be bound to the model identified by the `ngModel`
- * directive.
- *
- * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
- * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
- * option. See example below for demonstration.
- *
- * ## Complex Models (objects or collections)
- *
- * **Note:** By default, `ngModel` watches the model by reference, not value. This is important when
- * binding any input directive to a model that is an object or a collection.
- *
- * Since this is a common situation for `ngOptions` the directive additionally watches the model using
- * `$watchCollection` when the select has the `multiple` attribute or when there is a `track by` clause in
- * the options expression. This allows ngOptions to trigger a re-rendering of the options even if the actual
- * object/collection has not changed identity but only a property on the object or an item in the collection
- * changes.
- *
- * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
- * if the model is an array). This means that changing a property deeper inside the object/collection that the
- * first level will not trigger a re-rendering.
- *
- *
- * ## `select` **`as`**
- *
- * Using `select` **`as`** will bind the result of the `select` expression to the model, but
- * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
- * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
- * is used, the result of that expression will be set as the value of the `option` and `select` elements.
- *
- *
- * ### `select` **`as`** and **`track by`**
- *
- * <div class="alert alert-warning">
- * Do not use `select` **`as`** and **`track by`** in the same expression. They are not designed to work together.
- * </div>
- *
- * Consider the following example:
- *
- * ```html
- * <select ng-options="item.subItem as item.label for item in values track by item.id" ng-model="selected"></select>
- * ```
- *
- * ```js
- * $scope.values = [{
- *   id: 1,
- *   label: 'aLabel',
- *   subItem: { name: 'aSubItem' }
- * }, {
- *   id: 2,
- *   label: 'bLabel',
- *   subItem: { name: 'bSubItem' }
- * }];
- *
- * $scope.selected = { name: 'aSubItem' };
- * ```
- *
- * With the purpose of preserving the selection, the **`track by`** expression is always applied to the element
- * of the data source (to `item` in this example). To calculate whether an element is selected, we do the
- * following:
- *
- * 1. Apply **`track by`** to the elements in the array. In the example: `[1, 2]`
- * 2. Apply **`track by`** to the already selected value in `ngModel`.
- *    In the example: this is not possible as **`track by`** refers to `item.id`, but the selected
- *    value from `ngModel` is `{name: 'aSubItem'}`, so the **`track by`** expression is applied to
- *    a wrong object, the selected element can't be found, `<select>` is always reset to the "not
- *    selected" option.
- *
- *
- * @param {string} ngModel Assignable angular expression to data-bind to.
- * @param {string=} name Property name of the form under which the control is published.
- * @param {string=} required The control is considered valid only if value is entered.
- * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
- *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
- *    `required` when you want to data-bind to the `required` attribute.
- * @param {comprehension_expression=} ngOptions in one of the following forms:
- *
- *   * for array data sources:
- *     * `label` **`for`** `value` **`in`** `array`
- *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
- *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
- *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`
- *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
- *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
- *     * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
- *        (for including a filter with `track by`)
- *   * for object data sources:
- *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
- *     * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`group by`** `group`
- *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`disable when`** `disable`
- *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
- *
- * Where:
- *
- *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
- *   * `value`: local variable which will refer to each item in the `array` or each property value
- *      of `object` during iteration.
- *   * `key`: local variable which will refer to a property name in `object` during iteration.
- *   * `label`: The result of this expression will be the label for `<option>` element. The
- *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
- *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
- *      element. If not specified, `select` expression will default to `value`.
- *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
- *      DOM element.
- *   * `disable`: The result of this expression will be used to disable the rendered `<option>`
- *      element. Return `true` to disable.
- *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
- *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
- *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved
- *      even when the options are recreated (e.g. reloaded from the server).

-/**
- * @ngdoc directive
- * @name ngPluralize
- * @restrict EA
- *
- * @description
- * `ngPluralize` is a directive that displays messages according to en-US localization rules.
- * These rules are bundled with angular.js, but can be overridden
- * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
- * by specifying the mappings between
- * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
- * and the strings to be displayed.
- *
- * # Plural categories and explicit number rules
- * There are two
- * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
- * in Angular's default en-US locale: "one" and "other".
- *
- * While a plural category may match many numbers (for example, in en-US locale, "other" can match
- * any number that is not 1), an explicit number rule can only match one number. For example, the
- * explicit number rule for "3" matches the number 3. There are examples of plural categories
- * and explicit number rules throughout the rest of this documentation.
- *
- * # Configuring ngPluralize
- * You configure ngPluralize by providing 2 attributes: `count` and `when`.
- * You can also provide an optional attribute, `offset`.
- *
- * The value of the `count` attribute can be either a string or an {@link guide/expression
- * Angular expression}; these are evaluated on the current scope for its bound value.
- *
- * The `when` attribute specifies the mappings between plural categories and the actual
- * string to be displayed. The value of the attribute should be a JSON object.
- *
- * The following example shows how to configure ngPluralize:
- *
- * ```html
- * <ng-pluralize count="personCount"
-                 when="{'0': 'Nobody is viewing.',
- *                      'one': '1 person is viewing.',
- *                      'other': '{} people are viewing.'}">
- * </ng-pluralize>
- *```
- *
- * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
- * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
- * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
- * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
- * show "a dozen people are viewing".
- *
- * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
- * into pluralized strings. In the previous example, Angular will replace `{}` with
- * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
- * for <span ng-non-bindable>{{numberExpression}}</span>.
- *
- * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
- * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
- *
- * # Configuring ngPluralize with offset
- * The `offset` attribute allows further customization of pluralized text, which can result in
- * a better user experience. For example, instead of the message "4 people are viewing this document",
- * you might display "John, Kate and 2 others are viewing this document".
- * The offset attribute allows you to offset a number by any desired value.
- * Let's take a look at an example:
- *
- * ```html
- * <ng-pluralize count="personCount" offset=2
- *               when="{'0': 'Nobody is viewing.',
- *                      '1': '{{person1}} is viewing.',
- *                      '2': '{{person1}} and {{person2}} are viewing.',
- *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
- *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
- * </ng-pluralize>
- * ```
- *
- * Notice that we are still using two plural categories(one, other), but we added
- * three explicit number rules 0, 1 and 2.
- * When one person, perhaps John, views the document, "John is viewing" will be shown.
- * When three people view the document, no explicit number rule is found, so
- * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
- * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
- * is shown.
- *
- * Note that when you specify offsets, you must provide explicit number rules for
- * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
- * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
- * plural categories "one" and "other".
- *
- * @param {string|expression} count The variable to be bound to.
- * @param {string} when The mapping between plural category to its corresponding strings.
- * @param {number=} offset Offset to deduct from the total number.
- *

- * @ngdoc directive
- * @name ngRepeat
- * @multiElement
- *
- * @description
- * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
- * instance gets its own scope, where the given loop variable is set to the current collection item,
- * and `$index` is set to the item index or key.
- *
- * Special properties are exposed on the local scope of each template instance, including:
- *
- * | Variable  | Type            | Details                                                                     |
- * |-----------|-----------------|-----------------------------------------------------------------------------|
- * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
- * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
- * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
- * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
- * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
- * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
- *
- * <div class="alert alert-info">
- *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
- *   This may be useful when, for instance, nesting ngRepeats.
- * </div>
- *
- *
- * # Iterating over object properties
- *
- * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
- * syntax:
- *
- * ```js
- * <div ng-repeat="(key, value) in myObj"> ... </div>
- * ```
- *
- * You need to be aware that the JavaScript specification does not define the order of keys
- * returned for an object. (To mitigate this in Angular 1.3 the `ngRepeat` directive
- * used to sort the keys alphabetically.)
- *
- * Version 1.4 removed the alphabetic sorting. We now rely on the order returned by the browser
- * when running `for key in myObj`. It seems that browsers generally follow the strategy of providing
- * keys in the order in which they were defined, although there are exceptions when keys are deleted
- * and reinstated. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_issues
- *
- * If this is not desired, the recommended workaround is to convert your object into an array
- * that is sorted into the order that you prefer before providing it to `ngRepeat`.  You could
- * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
- * or implement a `$watch` on the object yourself.
- *
- *
- * # Tracking and Duplicates
- *
- * When the contents of the collection change, `ngRepeat` makes the corresponding changes to the DOM:
- *
- * * When an item is added, a new instance of the template is added to the DOM.
- * * When an item is removed, its template instance is removed from the DOM.
- * * When items are reordered, their respective templates are reordered in the DOM.
- *
- * By default, `ngRepeat` does not allow duplicate items in arrays. This is because when
- * there are duplicates, it is not possible to maintain a one-to-one mapping between collection
- * items and DOM elements.
- *
- * If you do need to repeat duplicate items, you can substitute the default tracking behavior
- * with your own using the `track by` expression.
- *
- * For example, you may track items by the index of each item in the collection, using the
- * special scope property `$index`:
- * ```html
- *    <div ng-repeat="n in [42, 42, 43, 43] track by $index">
- *      {{n}}
- *    </div>
- * ```
- *
- * You may use arbitrary expressions in `track by`, including references to custom functions
- * on the scope:
- * ```html
- *    <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
- *      {{n}}
- *    </div>
- * ```
- *
- * If you are working with objects that have an identifier property, you can track
- * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat`
- * will not have to rebuild the DOM elements for items it has already rendered, even if the
- * JavaScript objects in the collection have been substituted for new ones:
- * ```html
- *    <div ng-repeat="model in collection track by model.id">
- *      {{model.name}}
- *    </div>
- * ```
- *
- * When no `track by` expression is provided, it is equivalent to tracking by the built-in
- * `$id` function, which tracks items by their identity:
- * ```html
- *    <div ng-repeat="obj in collection track by $id(obj)">
- *      {{obj.prop}}
- *    </div>
- * ```
- *
- * <div class="alert alert-warning">
- * **Note:** `track by` must always be the last expression:
- * </div>
- * ```
- * <div ng-repeat="model in collection | orderBy: 'id' as filtered_result track by model.id">
- *     {{model.name}}
- * </div>
- * ```
- *
- * # Special repeat start and end points
- * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
- * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
- * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
- * up to and including the ending HTML tag where **ng-repeat-end** is placed.
- *
- * The example below makes use of this feature:
- * ```html
- *   <header ng-repeat-start="item in items">
- *     Header {{ item }}
- *   </header>
- *   <div class="body">
- *     Body {{ item }}
- *   </div>
- *   <footer ng-repeat-end>
- *     Footer {{ item }}
- *   </footer>
- * ```
- *
- * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
- * ```html
- *   <header>
- *     Header A
- *   </header>
- *   <div class="body">
- *     Body A
- *   </div>
- *   <footer>
- *     Footer A
- *   </footer>
- *   <header>
- *     Header B
- *   </header>
- *   <div class="body">
- *     Body B
- *   </div>
- *   <footer>
- *     Footer B
- *   </footer>
- * ```
- *
- * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
- * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
- *
- * @animations
- * **.enter** - when a new item is added to the list or when an item is revealed after a filter
- *
- * **.leave** - when an item is removed from the list or when an item is filtered out
- *
- * **.move** - when an adjacent item is filtered out causing a reorder or when the item contents are reordered
- *
- * @element ANY
- * @scope
- * @priority 1000
- * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
- *   formats are currently supported:
- *
- *   * `variable in expression` – where variable is the user defined loop variable and `expression`
- *     is a scope expression giving the collection to enumerate.
- *
- *     For example: `album in artist.albums`.
- *
- *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
- *     and `expression` is the scope expression giving the collection to enumerate.
- *
- *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
- *
- *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
- *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
- *     is specified, ng-repeat associates elements by identity. It is an error to have
- *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
- *     mapped to the same DOM element, which is not possible.)
- *
- *     Note that the tracking expression must come last, after any filters, and the alias expression.
- *
- *     For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
- *     will be associated by item identity in the array.
- *
- *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
- *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
- *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
- *     element in the same way in the DOM.
- *
- *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
- *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
- *     property is same.
- *
- *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
- *     to items in conjunction with a tracking expression.
- *
- *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
- *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
- *     when a filter is active on the repeater, but the filtered result set is empty.
- *
- *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
- *     the items have been processed through the filter.
- *
- *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end
- *     (and not as operator, inside an expression).
- *
- *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .
- *
- * @example
- * This example initializes the scope to a list of names and
- * then uses `ngRepeat` to display every person:

-/**
- * @ngdoc directive
- * @name ngShow
- * @multiElement
- *
- * @description
- * The `ngShow` directive shows or hides the given HTML element based on the expression
- * provided to the `ngShow` attribute. The element is shown or hidden by removing or adding
- * the `.ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
- * in AngularJS and sets the display style to none (using an !important flag).
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * <!-- when $scope.myValue is truthy (element is visible) -->
- * <div ng-show="myValue"></div>
- *
- * <!-- when $scope.myValue is falsy (element is hidden) -->
- * <div ng-show="myValue" class="ng-hide"></div>
- * ```
- *
- * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added to the class
- * attribute on the element causing it to become hidden. When truthy, the `.ng-hide` CSS class is removed
- * from the element causing the element not to appear hidden.
- *
- * ## Why is !important used?
- *
- * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector
- * can be easily overridden by heavier selectors. For example, something as simple
- * as changing the display style on a HTML list item would make hidden elements appear visible.
- * This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
- * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
- * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
- *
- * ### Overriding `.ng-hide`
- *
- * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change
- * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
- * class CSS. Note that the selector that needs to be used is actually `.ng-hide:not(.ng-hide-animate)` to cope
- * with extra animation classes that can be added.
- *
- * ```css
- * .ng-hide:not(.ng-hide-animate) {
- *   /&#42; this is just another form of hiding an element &#42;/
- *   display: block!important;
- *   position: absolute;
- *   top: -9999px;
- *   left: -9999px;
- * }
- * ```
- *
- * By default you don't need to override in CSS anything and the animations will work around the display style.
- *
- * ## A note about animations with `ngShow`
- *
- * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
- * is true and false. This system works like the animation system present with ngClass except that
- * you must also include the !important flag to override the display property
- * so that you can perform an animation when the element is hidden during the time of the animation.
- *
- * ```css
- * //
- * //a working example can be found at the bottom of this page
- * //
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   /&#42; this is required as of 1.3x to properly
- *      apply all styling in a show/hide animation &#42;/
- *   transition: 0s linear all;
- * }

-/**
- * @ngdoc directive
- * @name ngHide
- * @multiElement
- *
- * @description
- * The `ngHide` directive shows or hides the given HTML element based on the expression
- * provided to the `ngHide` attribute. The element is shown or hidden by removing or adding
- * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
- * in AngularJS and sets the display style to none (using an !important flag).
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * <!-- when $scope.myValue is truthy (element is hidden) -->
- * <div ng-hide="myValue" class="ng-hide"></div>
- *
- * <!-- when $scope.myValue is falsy (element is visible) -->
- * <div ng-hide="myValue"></div>
- * ```
- *
- * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added to the class
- * attribute on the element causing it to become hidden. When falsy, the `.ng-hide` CSS class is removed
- * from the element causing the element not to appear hidden.
- *
- * ## Why is !important used?
- *
- * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector
- * can be easily overridden by heavier selectors. For example, something as simple
- * as changing the display style on a HTML list item would make hidden elements appear visible.
- * This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
- * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
- * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
- *
- * ### Overriding `.ng-hide`
- *
- * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change
- * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
- * class in CSS:
- *
- * ```css
- * .ng-hide {
- *   /&#42; this is just another form of hiding an element &#42;/
- *   display: block!important;
- *   position: absolute;
- *   top: -9999px;
- *   left: -9999px;
- * }
- * ```
- *
- * By default you don't need to override in CSS anything and the animations will work around the display style.
- *
- * ## A note about animations with `ngHide`
- *
- * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
- * is true and false. This system works like the animation system present with ngClass, except that the `.ng-hide`
- * CSS class is added and removed for you instead of your own CSS class.
- *
- * ```css
- * //
- * //a working example can be found at the bottom of this page
- * //
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   transition: 0.5s linear all;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3.0-beta.11, there is no need to change the display
- * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
- *
- * @animations
- * removeClass: `.ng-hide` - happens after the `ngHide` expression evaluates to a truthy value and just before the contents are set to hidden
- * addClass: `.ng-hide` - happens after the `ngHide` expression evaluates to a non truthy value and just before the contents are set to visible
- *
- * @element ANY
- * @param {expression} ngHide If the {@link guide/expression expression} is truthy then
- *     the element is shown or hidden respectively.

-/**
- * @ngdoc directive
- * @name ngSwitch
- * @restrict EA
- *
- * @description
- * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
- * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
- * as specified in the template.
- *
- * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
- * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
- * matches the value obtained from the evaluated expression. In other words, you define a container element
- * (where you place the directive), place an expression on the **`on="..."` attribute**
- * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
- * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
- * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
- * attribute is displayed.
- *
- * <div class="alert alert-info">
- * Be aware that the attribute values to match against cannot be expressions. They are interpreted
- * as literal string values to match against.
- * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
- * value of the expression `$scope.someVal`.
- * </div>
-
- * @animations
- * enter - happens after the ngSwitch contents change and the matched child element is placed inside the container
- * leave - happens just after the ngSwitch contents change and just before the former contents are removed from the DOM
- *
- * @usage
- *
- * ```
- * <ANY ng-switch="expression">
- *   <ANY ng-switch-when="matchValue1">...</ANY>
- *   <ANY ng-switch-when="matchValue2">...</ANY>
- *   <ANY ng-switch-default>...</ANY>
- * </ANY>
- * ```
- *
- *
- * @scope
- * @priority 1200
- * @param {*} ngSwitch|on expression to match against <code>ng-switch-when</code>.
- * On child elements add:
- *
- * * `ngSwitchWhen`: the case statement to match against. If match then this
- *   case will be displayed. If the same match appears multiple times, all the
- *   elements will be displayed.
- * * `ngSwitchDefault`: the default case when no other case match. If there
- *   are multiple default cases, all of them will be displayed when no other
- *   case match.

-/**
- * @ngdoc directive
- * @name select
- * @restrict E
- *
- * @description
- * HTML `SELECT` element with angular data-binding.
- *
- * The `select` directive is used together with {@link ngModel `ngModel`} to provide data-binding
- * between the scope and the `<select>` control (including setting default values).
- * Ìt also handles dynamic `<option>` elements, which can be added using the {@link ngRepeat `ngRepeat}` or
- * {@link ngOptions `ngOptions`} directives.
- *
- * When an item in the `<select>` menu is selected, the value of the selected option will be bound
- * to the model identified by the `ngModel` directive. With static or repeated options, this is
- * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
- * If you want dynamic value attributes, you can use interpolation inside the value attribute.
- *
- * <div class="alert alert-warning">
- * Note that the value of a `select` directive used without `ngOptions` is always a string.
- * When the model needs to be bound to a non-string value, you must either explictly convert it
- * using a directive (see example below) or use `ngOptions` to specify the set of options.
- * This is because an option element can only be bound to string values at present.
- * </div>
- *
- * If the viewValue of `ngModel` does not match any of the options, then the control
- * will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
- *
- * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
- * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
- * option. See example below for demonstration.
- *
- * <div class="alert alert-info">
- * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
- * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits, such as
- * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
- * comprehension expression, and additionally in reducing memory and increasing speed by not creating
- * a new scope for each repeated instance.
- * </div>
- *
- *
- * @param {string} ngModel Assignable angular expression to data-bind to.
- * @param {string=} name Property name of the form under which the control is published.
- * @param {string=} required Sets `required` validation error key if the value is not entered.
- * @param {string=} ngRequired Adds required attribute and required validation constraint to
- * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
- * when you want to data-bind to the required attribute.
- * @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user
- *    interaction with the select element.
- * @param {string=} ngOptions sets the options that the select is populated with and defines what is
- * set on the model on selection. See {@link ngOptions `ngOptions`}.
- *
- * @example
- * ### Simple `select` elements with static options
- *
- * <example name="static-select" module="staticSelect">
- * <file name="index.html">
- * <div ng-controller="ExampleController">

- *
- *
- * ### Using `select` with `ngOptions` and setting a default value
- * See the {@link ngOptions ngOptions documentation} for more `ngOptions` usage examples.

- *       };
- *   }]);
- * </file>
- *</example>
- *
- *

-   * @ngdoc function
-   * @name ui.router.util.$resolve#resolve
-   * @methodOf ui.router.util.$resolve
-   *
-   * @description
-   * Resolves a set of invocables. An invocable is a function to be invoked via 
-   * `$injector.invoke()`, and can have an arbitrary number of dependencies. 
-   * An invocable can either return a value directly,
-   * or a `$q` promise. If a promise is returned it will be resolved and the 
-   * resulting value will be used instead. Dependencies of invocables are resolved 
-   * (in this order of precedence)
-   *
-   * - from the specified `locals`
-   * - from another invocable that is part of this `$resolve` call
-   * - from an invocable that is inherited from a `parent` call to `$resolve` 
-   *   (or recursively
-   * - from any ancestor `$resolve` of that parent).
-   *
-   * The return value of `$resolve` is a promise for an object that contains 
-   * (in this order of precedence)
-   *
-   * - any `locals` (if specified)
-   * - the resolved return values of all injectables
-   * - any values inherited from a `parent` call to `$resolve` (if specified)
-   *
-   * The promise will resolve after the `parent` promise (if any) and all promises 
-   * returned by injectables have been resolved. If any invocable 
-   * (or `$injector.invoke`) throws an exception, or if a promise returned by an 
-   * invocable is rejected, the `$resolve` promise is immediately rejected with the 
-   * same error. A rejection of a `parent` promise (if specified) will likewise be 
-   * propagated immediately. Once the `$resolve` promise has been rejected, no 
-   * further invocables will be called.
-   * 
-   * Cyclic dependencies between invocables are not permitted and will caues `$resolve`
-   * to throw an error. As a special case, an injectable can depend on a parameter 
-   * with the same name as the injectable, which will be fulfilled from the `parent` 
-   * injectable of the same name. This allows inherited values to be decorated. 
-   * Note that in this case any other injectable in the same `$resolve` with the same
-   * dependency would see the decorated value, not the inherited value.
-   *
-   * Note that missing dependencies -- unlike cyclic dependencies -- will cause an 
-   * (asynchronous) rejection of the `$resolve` promise rather than a (synchronous) 
-   * exception.
-   *
-   * Invocables are invoked eagerly as soon as all dependencies are available. 
-   * This is true even for dependencies inherited from a `parent` call to `$resolve`.
-   *
-   * As a special case, an invocable can be a string, in which case it is taken to 
-   * be a service name to be passed to `$injector.get()`. This is supported primarily 
-   * for backwards-compatibility with the `resolve` property of `$routeProvider` 
-   * routes.

-   * `$injector` services to fetch.
-   * @param {object} locals  values to make available to the injectables
-   * @param {object} parent  a promise returned by another call to `$resolve`.
-   * @param {object} self  the `this` for the invoked methods

-/**
- * @ngdoc object
- * @name ui.router.util.type:UrlMatcher
- *
- * @description
- * Matches URLs against patterns and extracts named parameters from the path or the search
- * part of the URL. A URL pattern consists of a path pattern, optionally followed by '?' and a list
- * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
- * do not influence whether or not a URL is matched, but their values are passed through into
- * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
- *
- * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
- * syntax, which optionally allows a regular expression for the parameter to be specified:
- *
- * * `':'` name - colon placeholder
- * * `'*'` name - catch-all placeholder
- * * `'{' name '}'` - curly placeholder
- * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
- *   regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
- *
- * Parameter names may contain only word characters (latin letters, digits, and underscore) and
- * must be unique within the pattern (across both path and search parameters). For colon
- * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
- * number of characters other than '/'. For catch-all placeholders the path parameter matches
- * any number of characters.
- *
- * Examples:
- *
- * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
- *   trailing slashes, and patterns have to match the entire path, not just a prefix.
- * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or
- *   '/user/bob/details'. The second path segment will be captured as the parameter 'id'.
- * * `'/user/{id}'` - Same as the previous example, but using curly brace syntax.
- * * `'/user/{id:[^/]*}'` - Same as the previous example.
- * * `'/user/{id:[0-9a-fA-F]{1,8}}'` - Similar to the previous example, but only matches if the id
- *   parameter consists of 1 to 8 hex digits.
- * * `'/files/{path:.*}'` - Matches any URL starting with '/files/' and captures the rest of the
- *   path into the parameter 'path'.
- * * `'/files/*path'` - ditto.
- * * `'/calendar/{start:date}'` - Matches "/calendar/2014-11-12" (because the pattern defined
- *   in the built-in  `date` Type matches `2014-11-12`) and provides a Date object in $stateParams.start
- *
- * @param {string} pattern  The pattern to compile into a matcher.
- * @param {Object} config  A configuration object hash:
- * @param {Object=} parentMatcher Used to concatenate the pattern/config onto
- *   an existing UrlMatcher
- *
- * * `caseInsensitive` - `true` if URL matching should be case insensitive, otherwise `false`, the default value (for backward compatibility) is `false`.
- * * `strict` - `false` if matching against a URL with a trailing slash should be treated as equivalent to a URL without a trailing slash, the default value is `true`.
- *
- * @property {string} prefix  A static prefix of this pattern. The matcher guarantees that any
- *   URL matching this matcher (i.e. any string for which {@link ui.router.util.type:UrlMatcher#methods_exec exec()} returns
- *   non-null) will start with this prefix.
- *
- * @property {string} source  The pattern that was passed into the constructor
- *
- * @property {string} sourcePath  The path portion of the source property
- *
- * @property {string} sourceSearch  The search portion of the source property
- *
- * @property {string} regex  The constructed regex that will be used to match against the url when
- *   it is time to determine which url will match.
- *
- * @returns {Object}  New `UrlMatcher` object

-   *
-   * @returns {Object}  Returns `$urlMatcherFactoryProvider`.

-   * <pre>
-   * var list = ['John', 'Paul', 'George', 'Ringo'];

-   *     // Ensure the item is valid by checking to see that it appears
-   *     // in the list
-   *     return list.indexOf(item) > -1;
-   *   }
-   * });
-   *
-   * $stateProvider.state('list', {
-   *   url: "/list/{item:listItem}",
-   *   controller: function($scope, $stateParams) {
-   *     console.log($stateParams.item);
-   *   }

-   * // ...
-   *
-   * // Changes URL to '/list/3', logs "Ringo" to the console
-   * $state.go('list', { item: "Ringo" });
-   * </pre>
-   *
-   * This is a more complex example of a type that relies on dependency injection to
-   * interact with services, and uses the parameter name from the URL to infer how to
-   * handle encoding and decoding parameter values:
-   *
-   * <pre>
-   * // Defines a custom type that gets a value from a service,
-   * // where each service gets different types of values from
-   * // a backend API:

-   *   var services = {

-   * @ngdoc function
-   * @name ui.router.state.$stateProvider#decorator
-   * @methodOf ui.router.state.$stateProvider
-   *
-   * @description
-   * Allows you to extend (carefully) or override (at your own peril) the 
-   * `stateBuilder` object used internally by `$stateProvider`. This can be used 
-   * to add custom functionality to ui-router, for example inferring templateUrl 
-   * based on the state name.
-   *
-   * When passing only a name, it returns the current (original or decorated) builder
-   * function that matches `name`.
-   *
-   * The builder functions that can be decorated are listed below. Though not all
-   * necessarily have a good use case for decoration, that is up to you to decide.
-   *
-   * In addition, users can attach custom decorators, which will generate new 
-   * properties within the state's internal definition. There is currently no clear 
-   * use-case for this beyond accessing internal states (i.e. $state.$current), 
-   * however, expect this to become increasingly relevant as we introduce additional 
-   * meta-programming features.
-   *
-   * **Warning**: Decorators should not be interdependent because the order of 
-   * execution of the builder functions in non-deterministic. Builder functions 
-   * should only be dependent on the state definition object and super function.
-   *
-   *
-   * Existing builder functions and current return values:
-   *
-   * - **parent** `{object}` - returns the parent state object.
-   * - **data** `{object}` - returns state data, including any inherited data that is not
-   *   overridden by own values (if any).
-   * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
-   *   or `null`.
-   * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is 
-   *   navigable).
-   * - **params** `{object}` - returns an array of state params that are ensured to 
-   *   be a super-set of parent's params.
-   * - **views** `{object}` - returns a views object where each key is an absolute view 
-   *   name (i.e. "viewName@stateName") and each value is the config object 
-   *   (template, controller) for the view. Even when you don't use the views object 
-   *   explicitly on a state config, one is still created for you internally.
-   *   So by decorating this builder function you have access to decorating template 
-   *   and controller properties.
-   * - **ownParams** `{object}` - returns an array of params that belong to the state, 
-   *   not including any params defined by ancestor states.
-   * - **path** `{string}` - returns the full path from the root down to this state. 
-   *   Needed for state activation.
-   * - **includes** `{object}` - returns an object that includes every state that 
-   *   would pass a `$state.includes()` test.
-   *
-   * @example
-   * <pre>
-   * // Override the internal 'views' builder with a function that takes the state
-   * // definition, and a reference to the internal function being overridden:
-   * $stateProvider.decorator('views', function (state, parent) {
-   *   var result = {},
-   *       views = parent(state);
-   *
-   *   angular.forEach(views, function (config, name) {
-   *     var autoName = (state.name + '.' + name).replace('.', '/');
-   *     config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';
-   *     result[name] = config;
-   *   });
-   *   return result;
-   * });
-   *
-   * $stateProvider.state('home', {
-   *   views: {
-   *     'contact.list': { controller: 'ListController' },
-   *     'contact.item': { controller: 'ItemController' }
-   *   }
-   * });

-   * // Auto-populates list and item views with /partials/home/contact/list.html,
-   * // and /partials/home/contact/item.html, respectively.
-   * </pre>
-   *
-   * @param {string} name The name of the builder function to decorate. 
-   * @param {object} func A function that is responsible for decorating the original 
-   * builder function. The function receives two parameters:
-   *
-   *   - `{object}` - state - The state config object.

-   * Injectable provider function that returns the actual controller or string.
-   * <pre>controllerProvider:
-   *   function(MyResolveData) {
-   *     if (MyResolveData.foo)
-   *       return "FooCtrl"
-   *     else if (MyResolveData.bar)
-   *       return "BarCtrl";
-   *     else return function($scope) {
-   *       $scope.baz = "Qux";
-   *     }
-   *   }</pre>
-   *
-   * @param {string=} stateConfig.controllerAs
-   * <a id='controllerAs'></a>
-   * 
-   * A controller alias name. If present the controller will be
-   *   published to scope under the controllerAs name.
-   * <pre>controllerAs: "myCtrl"</pre>
-   *
-   * @param {string|object=} stateConfig.parent
-   * <a id='parent'></a>
-   * Optionally specifies the parent state of this state.
-   *
-   * <pre>parent: 'parentState'</pre>
-   * <pre>parent: parentState // JS variable</pre>
-   *
-   * @param {object=} stateConfig.resolve
-   * <a id='resolve'></a>
-   *
-   * An optional map&lt;string, function&gt; of dependencies which
-   *   should be injected into the controller. If any of these dependencies are promises, 
-   *   the router will wait for them all to be resolved before the controller is instantiated.
-   *   If all the promises are resolved successfully, the $stateChangeSuccess event is fired
-   *   and the values of the resolved promises are injected into any controllers that reference them.
-   *   If any  of the promises are rejected the $stateChangeError event is fired.
-   *
-   *   The map object is:
-   *   
-   *   - key - {string}: name of dependency to be injected into controller
-   *   - factory - {string|function}: If string then it is alias for service. Otherwise if function, 
-   *     it is injected and return value it treated as dependency. If result is a promise, it is 
-   *     resolved before its value is injected into controller.
-   *
-   * <pre>resolve: {
-   *     myResolve1:
-   *       function($http, $stateParams) {
-   *         return $http.get("/api/foos/"+stateParams.fooID);
-   *       }
-   *     }</pre>
-   *
-   * @param {string=} stateConfig.url
-   * <a id='url'></a>
-   *
-   *   A url fragment with optional parameters. When a state is navigated or
-   *   transitioned to, the `$stateParams` service will be populated with any 
-   *   parameters that were passed.
-   *
-   *   (See {@link ui.router.util.type:UrlMatcher UrlMatcher} `UrlMatcher`} for
-   *   more details on acceptable patterns )
-   *
-   * examples:
-   * <pre>url: "/home"
-   * url: "/users/:userid"
-   * url: "/books/{bookid:[a-zA-Z_-]}"
-   * url: "/books/{categoryid:int}"
-   * url: "/books/{publishername:string}/{categoryid:int}"
-   * url: "/messages?before&after"
-   * url: "/messages?{before:date}&{after:date}"
-   * url: "/messages/:mailboxid?{before:date}&{after:date}"
-   * </pre>
-   *
-   * @param {object=} stateConfig.views
-   * <a id='views'></a>
-   * an optional map&lt;string, object&gt; which defined multiple views, or targets views
-   * manually/explicitly.
-   *
-   * Examples:
-   *
-   * Targets three named `ui-view`s in the parent state's template
-   * <pre>views: {
-   *     header: {
-   *       controller: "headerCtrl",
-   *       templateUrl: "header.html"
-   *     }, body: {
-   *       controller: "bodyCtrl",
-   *       templateUrl: "body.html"
-   *     }, footer: {
-   *       controller: "footCtrl",
-   *       templateUrl: "footer.html"
-   *     }
-   *   }</pre>
-   *
-   * Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
-   * <pre>views: {
-   *     'header@top': {
-   *       controller: "msgHeaderCtrl",
-   *       templateUrl: "msgHeader.html"
-   *     }, 'body': {
-   *       controller: "messagesCtrl",
-   *       templateUrl: "messages.html"
-   *     }
-   *   }</pre>
-   *
-   * @param {boolean=} [stateConfig.abstract=false]
-   * <a id='abstract'></a>
-   * An abstract state will never be directly activated,
-   *   but can provide inherited properties to its common children states.
-   * <pre>abstract: true</pre>
-   *
-   * @param {function=} stateConfig.onEnter
-   * <a id='onEnter'></a>
-   *
-   * Callback function for when a state is entered. Good way
-   *   to trigger an action or dispatch an event, such as opening a dialog.
-   * If minifying your scripts, make sure to explictly annotate this function,
-   * because it won't be automatically annotated by your build tools.
-   *
-   * <pre>onEnter: function(MyService, $stateParams) {
-   *     MyService.foo($stateParams.myParam);
-   * }</pre>
-   *
-   * @param {function=} stateConfig.onExit
-   * <a id='onExit'></a>
-   *
-   * Callback function for when a state is exited. Good way to
-   *   trigger an action or dispatch an event, such as opening a dialog.
-   * If minifying your scripts, make sure to explictly annotate this function,
-   * because it won't be automatically annotated by your build tools.
-   *
-   * <pre>onExit: function(MyService, $stateParams) {
-   *     MyService.cleanup($stateParams.myParam);
-   * }</pre>
-   *
-   * @param {boolean=} [stateConfig.reloadOnSearch=true]
-   * <a id='reloadOnSearch'></a>
-   *
-   * If `false`, will not retrigger the same state
-   *   just because a search/query parameter has changed (via $location.search() or $location.hash()). 
-   *   Useful for when you'd like to modify $location.search() without triggering a reload.
-   * <pre>reloadOnSearch: false</pre>
-   *
-   * @param {object=} stateConfig.data
-   * <a id='data'></a>
-   *
-   * Arbitrary data object, useful for custom configuration.  The parent state's `data` is
-   *   prototypally inherited.  In other words, adding a data property to a state adds it to
-   *   the entire subtree via prototypal inheritance.
-   *
-   * <pre>data: {
-   *     requiredRole: 'foo'
-   * } </pre>
-   *
-   * @param {object=} stateConfig.params
-   * <a id='params'></a>
-   *
-   * A map which optionally configures parameters declared in the `url`, or
-   *   defines additional non-url parameters.  For each parameter being
-   *   configured, add a configuration object keyed to the name of the parameter.
-   *
-   *   Each parameter configuration object may contain the following properties:
-   *
-   *   - ** value ** - {object|function=}: specifies the default value for this
-   *     parameter.  This implicitly sets this parameter as optional.
-   *
-   *     When UI-Router routes to a state and no value is
-   *     specified for this parameter in the URL or transition, the
-   *     default value will be used instead.  If `value` is a function,
-   *     it will be injected and invoked, and the return value used.
-   *
-   *     *Note*: `undefined` is treated as "no default value" while `null`
-   *     is treated as "the default value is `null`".
-   *
-   *     *Shorthand*: If you only need to configure the default value of the
-   *     parameter, you may use a shorthand syntax.   In the **`params`**
-   *     map, instead mapping the param name to a full parameter configuration
-   *     object, simply set map it to the default parameter value, e.g.:
-   *
-   * <pre>// define a parameter's default value
-   * params: {
-   *     param1: { value: "defaultValue" }
-   * }
-   * // shorthand default values
-   * params: {
-   *     param1: "defaultValue",
-   *     param2: "param2Default"
-   * }</pre>
-   *
-   *   - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
-   *     treated as an array of values.  If you specified a Type, the value will be
-   *     treated as an array of the specified Type.  Note: query parameter values
-   *     default to a special `"auto"` mode.
-   *
-   *     For query parameters in `"auto"` mode, if multiple  values for a single parameter
-   *     are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
-   *     are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`).  However, if
-   *     only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
-   *     value (e.g.: `{ foo: '1' }`).
-   *
-   * <pre>params: {
-   *     param1: { array: true }
-   * }</pre>
-   *
-   *   - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
-   *     the current parameter value is the same as the default value. If `squash` is not set, it uses the
-   *     configured default squash policy.
-   *     (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
-   *
-   *   There are three squash settings:
-   *
-   *     - false: The parameter's default value is not squashed.  It is encoded and included in the URL
-   *     - true: The parameter's default value is omitted from the URL.  If the parameter is preceeded and followed
-   *       by slashes in the state's `url` declaration, then one of those slashes are omitted.
-   *       This can allow for cleaner looking URLs.
-   *     - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of  your choice.
-   *
-   * <pre>params: {
-   *     param1: {
-   *       value: "defaultId",
-   *       squash: true
-   * } }
-   * // squash "defaultValue" to "~"
-   * params: {
-   *     param1: {
-   *       value: "defaultValue",
-   *       squash: "~"
-   * } }
-   * </pre>
-   *
-   *
-   * @example
-   * <pre>
-   * // Some state name examples
-   *
-   * // stateName can be a single top-level name (must be unique).
-   * $stateProvider.state("home", {});
-   *
-   * // Or it can be a nested state name. This state is a child of the
-   * // above "home" state.
-   * $stateProvider.state("home.newest", {});
-   *
-   * // Nest states as deeply as needed.
-   * $stateProvider.state("home.newest.abc.xyz.inception", {});
-   *
-   * // state() returns $stateProvider, so you can chain state declarations.
-   * $stateProvider
-   *   .state("home", {})
-   *   .state("about", {})
-   *   .state("contacts", {});

-     * @description
-     * Convenience method for transitioning to a new state. `$state.go` calls 
-     * `$state.transitionTo` internally but automatically sets options to 
-     * `{ location: true, inherit: true, relative: $state.$current, notify: true }`. 
-     * This allows you to easily use an absolute or relative to path and specify 
-     * only the parameters you'd like to update (while letting unspecified parameters 
-     * inherit from the currently active ancestor states).
-     *
-     * @example
-     * <pre>
-     * var app = angular.module('app', ['ui.router']);
-     *
-     * app.controller('ctrl', function ($scope, $state) {

-     * @param {string} to Absolute state name or relative state path. Some examples:
-     *
-     * - `$state.go('contact.detail')` - will go to the `contact.detail` state
-     * - `$state.go('^')` - will go to a parent state
-     * - `$state.go('^.sibling')` - will go to a sibling state
-     * - `$state.go('.child.grandchild')` - will go to grandchild state
-     *
-     * @param {object=} params A map of the parameters that will be sent to the state, 
-     * will populate $stateParams. Any parameters that are not specified will be inherited from currently 
-     * defined parameters. This allows, for example, going to a sibling state that shares parameters
-     * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
-     * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
-     * will get you all current parameters, etc.
-     * @param {object=} options Options object. The options are:
-     *
-     * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
-     *    will not. If string, must be `"replace"`, which will update url and also replace last history record.
-     * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
-     * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'), 
-     *    defines which state to be relative from.
-     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
-     * - **`reload`** (v0.2.5) - {boolean=false}, If `true` will force transition even if the state or params 
-     *    have not changed, aka a reload of the same state. It differs from reloadOnSearch because you'd
-     *    use this when you want to force a reload when *everything* is the same, including search params.
-     *
-     * @returns {promise} A promise representing the state of the new transition.
-     *
-     * Possible success values:
-     *
-     * - $state.current
-     *
-     * <br/>Possible rejection values:
-     *
-     * - 'transition superseded' - when a newer transition has been started after this one
-     * - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener
-     * - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or
-     *   when a `$stateNotFound` `event.retry` promise errors.

-     * - **`inherit`** - {boolean=false}, If `true` will inherit url parameters from current url.
-     * - **`relative`** - {object=}, When transitioning with relative path (e.g '^'), 
-     *    defines which state to be relative from.
-     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
-     * - **`reload`** (v0.2.5) - {boolean=false|string=|object=}, If `true` will force transition even if the state or params 
-     *    have not changed, aka a reload of the same state. It differs from reloadOnSearch because you'd

- * @requires ui.router.state.$uiViewScroll
- * @requires $document
- *
- * @restrict ECA
- *
- * @description
- * The ui-view directive tells $state where to place your templates.
- *
- * @param {string=} name A view name. The name should be unique amongst the other views in the
- * same state. You can have views of the same name that live in different states.
- *
- * @param {string=} autoscroll It allows you to set the scroll behavior of the browser window
- * when a view is populated. By default, $anchorScroll is overridden by ui-router's custom scroll
- * service, {@link ui.router.state.$uiViewScroll}. This custom service let's you
- * scroll ui-view elements into view when they are populated during a state activation.
- *
- * *Note: To revert back to old [`$anchorScroll`](http://docs.angularjs.org/api/ng.$anchorScroll)
- * functionality, call `$uiViewScrollProvider.useAnchorScroll()`.*
- *
- * @param {string=} onload Expression to evaluate whenever the view updates.
- * 
- * @example
- * A view can be unnamed or named. 
- * <pre>
- * <!-- Unnamed -->
- * <div ui-view></div> 
- * 
- * <!-- Named -->
- * <div ui-view="viewName"></div>
- * </pre>
- *
- * You can only have one unnamed view within any template (or root html). If you are only using a 
- * single view and it is unnamed then you can populate it like so:
- * <pre>
- * <div ui-view></div> 
- * $stateProvider.state("home", {
- *   template: "<h1>HELLO!</h1>"
- * })
- * </pre>
- * 
- * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#views `views`}
- * config property, by name, in this case an empty name:
- * <pre>
- * $stateProvider.state("home", {
- *   views: {
- *     "": {
- *       template: "<h1>HELLO!</h1>"
- *     }
- *   }    
- * })
- * </pre>
- * 
- * But typically you'll only use the views property if you name your view or have more than one view 
- * in the same template. There's not really a compelling reason to name a view if its the only one, 
- * but you could if you wanted, like so:
- * <pre>
- * <div ui-view="main"></div>
- * </pre> 
- * <pre>
- * $stateProvider.state("home", {
- *   views: {
- *     "main": {
- *       template: "<h1>HELLO!</h1>"
- *     }
- *   }    
- * })
- * </pre>
- * 
- * Really though, you'll use views to set up multiple views:
- * <pre>
- * <div ui-view></div>
- * <div ui-view="chart"></div> 
- * <div ui-view="data"></div> 
- * </pre>
- * 
- * <pre>
- * $stateProvider.state("home", {
- *   views: {
- *     "": {
- *       template: "<h1>HELLO!</h1>"
- *     },
- *     "chart": {
- *       template: "<chart_thing/>"
- *     },
- *     "data": {
- *       template: "<data_thing/>"
- *     }
- *   }    
- * })
- * </pre>
- *
- * Examples for `autoscroll`:
- *
- * <pre>
- * <!-- If autoscroll present with no expression,
- *      then scroll ui-view into view -->
- * <ui-view autoscroll/>
- *
- * <!-- If autoscroll present with valid expression,
- *      then scroll ui-view into view if expression evaluates to true -->
- * <ui-view autoscroll='true'/>
- * <ui-view autoscroll='false'/>
- * <ui-view autoscroll='scopeVariable'/>
- * </pre>

- * @ngdoc directive
- * @name ui.router.state.directive:ui-sref
- *
- * @requires ui.router.state.$state
- * @requires $timeout
- *
- * @restrict A
- *
- * @description
- * A directive that binds a link (`<a>` tag) to a state. If the state has an associated 
- * URL, the directive will automatically generate & update the `href` attribute via 
- * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking 
- * the link will trigger a state transition with optional parameters. 
- *
- * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be 
- * handled natively by the browser.
- *
- * You can also use relative state paths within ui-sref, just like the relative 
- * paths passed to `$state.go()`. You just need to be aware that the path is relative
- * to the state that the link lives in, in other words the state that loaded the 
- * template containing the link.
- *
- * You can specify options to pass to {@link ui.router.state.$state#go $state.go()}
- * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
- * and `reload`.
- *
- * @example
- * Here's an example of how you'd use ui-sref and how it would compile. If you have the 
- * following template:
- * <pre>
- * <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
- *

- * @ngdoc directive
- * @name ui.router.state.directive:ui-sref-active
- *
- * @requires ui.router.state.$state
- * @requires ui.router.state.$stateParams
- * @requires $interpolate
- *
- * @restrict A
- *
- * @description
- * A directive working alongside ui-sref to add classes to an element when the
- * related ui-sref directive's state is active, and removing them when it is inactive.
- * The primary use-case is to simplify the special appearance of navigation menus
- * relying on `ui-sref`, by having the "active" state's menu button appear different,
- * distinguishing it from the inactive menu items.
- *
- * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
- * ui-sref-active found at the same level or above the ui-sref will be used.
- *
- * Will activate when the ui-sref's target state or any child state is active. If you
- * need to activate only when the ui-sref target state is active and *not* any of
- * it's children, then you will use
- * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
- *
- * @example
- * Given the following template:
- * <pre>
- * <ul>
- *   <li ui-sref-active="active" class="item">
- *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
- *   </li>
- * </ul>
- * </pre>
- *
- *
- * When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
- * the resulting HTML will appear as (note the 'active' class):
- * <pre>
- * <ul>
- *   <li ui-sref-active="active" class="item active">
- *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
- *   </li>
- * </ul>
- * </pre>
- *
- * The class name is interpolated **once** during the directives link time (any further changes to the
- * interpolated value are ignored).
- *
- * Multiple classes may be specified in a space-separated format:
- * <pre>
- * <ul>
- *   <li ui-sref-active='class1 class2 class3'>
- *     <a ui-sref="app.user">link</a>
- *   </li>

-/**
- * @ngdoc service
- * @name $resource
- * @requires $http
- *
- * @description
- * A factory which creates a resource object that lets you interact with
- * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
- *
- * The returned resource object has action methods which provide high-level behaviors without
- * the need to interact with the low level {@link ng.$http $http} service.
- *
- * Requires the {@link ngResource `ngResource`} module to be installed.
- *
- * By default, trailing slashes will be stripped from the calculated URLs,
- * which can pose problems with server backends that do not expect that
- * behavior.  This can be disabled by configuring the `$resourceProvider` like
- * this:
- *
- * ```js
-     app.config(['$resourceProvider', function($resourceProvider) {
-       // Don't strip trailing slashes from calculated URLs
-       $resourceProvider.defaults.stripTrailingSlashes = false;
-     }]);
- * ```
- *
- * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
- *   `/user/:username`. If you are using a URL with a port number (e.g.
- *   `http://example.com:8080/api`), it will be respected.
- *
- *   If you are using a url with a suffix, just add the suffix, like this:
- *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
- *   or even `$resource('http://example.com/resource/:resource_id.:format')`
- *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
- *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you
- *   can escape it with `/\.`.
- *
- * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
- *   `actions` methods. If any of the parameter value is a function, it will be executed every time
- *   when a param value needs to be obtained for a request (unless the param was overridden).
- *
- *   Each key value in the parameter object is first bound to url template if present and then any
- *   excess keys are appended to the url search query after the `?`.
- *
- *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
- *   URL `/path/greet?salutation=Hello`.
- *
- *   If the parameter value is prefixed with `@` then the value for that parameter will be extracted
- *   from the corresponding property on the `data` object (provided when calling an action method).  For
- *   example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of `someParam`
- *   will be `data.someProp`.
- *
- * @param {Object.<Object>=} actions Hash with declaration of custom actions that should extend
- *   the default set of resource actions. The declaration should be created in the format of {@link
- *   ng.$http#usage $http.config}:
- *
- *       {action1: {method:?, params:?, isArray:?, headers:?, ...},
- *        action2: {method:?, params:?, isArray:?, headers:?, ...},
- *        ...}
- *
- *   Where:
- *
- *   - **`action`** – {string} – The name of action. This name becomes the name of the method on
- *     your resource object.
- *   - **`method`** – {string} – Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
- *     `DELETE`, `JSONP`, etc).
- *   - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
- *     the parameter value is a function, it will be executed every time when a param value needs to
- *     be obtained for a request (unless the param was overridden).
- *   - **`url`** – {string} – action specific `url` override. The url templating is supported just
- *     like for the resource-level urls.
- *   - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
- *     see `returns` section.
- *   - **`transformRequest`** –
- *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
- *     transform function or an array of such functions. The transform function takes the http
- *     request body and headers and returns its transformed (typically serialized) version.
- *     By default, transformRequest will contain one function that checks if the request data is
- *     an object and serializes to using `angular.toJson`. To prevent this behavior, set
- *     `transformRequest` to an empty array: `transformRequest: []`
- *   - **`transformResponse`** –
- *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
- *     transform function or an array of such functions. The transform function takes the http
- *     response body and headers and returns its transformed (typically deserialized) version.
- *     By default, transformResponse will contain one function that checks if the response looks like
- *     a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior, set
- *     `transformResponse` to an empty array: `transformResponse: []`
- *   - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
- *     GET request, otherwise if a cache instance built with
- *     {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
- *     caching.
- *   - **`timeout`** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} that
- *     should abort the request when resolved.
- *   - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
- *     XHR object. See
- *     [requests with credentials](https://developer.mozilla.org/en/http_access_control#section_5)
- *     for more information.
- *   - **`responseType`** - `{string}` - see
- *     [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
- *   - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
- *     `response` and `responseError`. Both `response` and `responseError` interceptors get called
- *     with `http response` object. See {@link ng.$http $http interceptors}.
- *
- * @param {Object} options Hash with custom settings that should extend the
- *   default `$resourceProvider` behavior.  The only supported option is
- *
- *   Where:
- *
- *   - **`stripTrailingSlashes`** – {boolean} – If true then the trailing
- *   slashes from any calculated URL will be stripped. (Defaults to true.)
- *
- * @returns {Object} A resource "class" object with methods for the default set of resource actions
- *   optionally extended with custom `actions`. The default set contains these actions:
- *   ```js
- *   { 'get':    {method:'GET'},
- *     'save':   {method:'POST'},
- *     'query':  {method:'GET', isArray:true},
- *     'remove': {method:'DELETE'},
- *     'delete': {method:'DELETE'} };
- *   ```
- *
- *   Calling these methods invoke an {@link ng.$http} with the specified http method,
- *   destination and parameters. When the data is returned from the server then the object is an
- *   instance of the resource class. The actions `save`, `remove` and `delete` are available on it
- *   as  methods with the `$` prefix. This allows you to easily perform CRUD operations (create,
- *   read, update, delete) on server-side data like this:
- *   ```js
- *   var User = $resource('/user/:userId', {userId:'@id'});
- *   var user = User.get({userId:123}, function() {
- *     user.abc = true;
- *     user.$save();
- *   });
- *   ```
- *
- *   It is important to realize that invoking a $resource object method immediately returns an
- *   empty reference (object or array depending on `isArray`). Once the data is returned from the
- *   server the existing reference is populated with the actual data. This is a useful trick since
- *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
- *   object results in no rendering, once the data arrives from the server then the object is
- *   populated with the data and the view automatically re-renders itself showing the new data. This
- *   means that in most cases one never has to write a callback function for the action methods.
- *
- *   The action methods on the class object or instance object can be invoked with the following
- *   parameters:
- *
- *   - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
- *   - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
- *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`
- *
- *
- *   Success callback is called with (value, responseHeaders) arguments, where the value is
- *   the populated resource instance or collection object. The error callback is called
- *   with (httpResponse) argument.
- *
- *   Class actions return empty instance (with additional properties below).
- *   Instance actions return promise of the action.
- *
- *   The Resource instances and collection have these additional properties:
- *
- *   - `$promise`: the {@link ng.$q promise} of the original server interaction that created this
- *     instance or collection.
- *
- *     On success, the promise is resolved with the same resource instance or collection object,
- *     updated with data from server. This makes it easy to use in
- *     {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view
- *     rendering until the resource(s) are loaded.
- *
- *     On failure, the promise is resolved with the {@link ng.$http http response} object, without
- *     the `resource` property.
- *
- *     If an interceptor object was provided, the promise will instead be resolved with the value
- *     returned by the interceptor.
- *
- *   - `$resolved`: `true` after first server interaction is completed (either with success or
- *      rejection), `false` before that. Knowing if the Resource has been resolved is useful in
- *      data-binding.
- *
- * @example
- *
- * # Credit card resource
- *
- * ```js
-     // Define CreditCard class
-     var CreditCard = $resource('/user/:userId/card/:cardId',
-      {userId:123, cardId:'@id'}, {
-       charge: {method:'POST', params:{charge:true}}
-      });
-
-     // We can retrieve a collection from the server
-     var cards = CreditCard.query(function() {
-       // GET: /user/123/card
-       // server returns: [ {id:456, number:'1234', name:'Smith'} ];
-
-       var card = cards[0];
-       // each item is an instance of CreditCard
-       expect(card instanceof CreditCard).toEqual(true);
-       card.name = "J. Smith";
-       // non GET methods are mapped onto the instances
-       card.$save();
-       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
-       // server returns: {id:456, number:'1234', name: 'J. Smith'};
-
-       // our custom method is mapped as well.

-       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
-     });

-     newCard.$save();
-     // POST: /user/123/card {number:'0123', name:'Mike Smith'}

-     expect(newCard.id).toEqual(789);
- * ```
- *
- * The object returned from this function execution is a resource "class" which has "static" method
- * for each action in the definition.
- *
- * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and
- * `headers`.
- * When the data is returned from the server then the object is an instance of the resource type and
- * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
- * operations (create, read, update, delete) on server-side data.
-
-   ```js
-     var User = $resource('/user/:userId', {userId:'@id'});
-     User.get({userId:123}, function(user) {
-       user.abc = true;
-       user.$save();
-     });
-   ```
- *
- * It's worth noting that the success callback for `get`, `query` and other methods gets passed
- * in the response that came from the server as well as $http header getter function, so one
- * could rewrite the above example and get access to http headers as:
- *
-   ```js
-     var User = $resource('/user/:userId', {userId:'@id'});
-     User.get({userId:123}, function(u, getResponseHeaders){
-       u.abc = true;
-       u.$save(function(u, putResponseHeaders) {
-         //u => saved user object
-         //putResponseHeaders => $http header getter
-       });
-     });
-   ```
- *
- * You can also access the raw `$http` promise via the `$promise` property on the object returned
- *
-   ```
-     var User = $resource('/user/:userId', {userId:'@id'});
-     User.get({userId:123})
-         .$promise.then(function(user) {
-           $scope.user = user;
-         });
-   ```
-
- * # Creating a custom 'PUT' request
- * In this example we create a custom method on our resource to make a PUT request
- * ```js
- *    var app = angular.module('app', ['ngResource', 'ngRoute']);
- *
- *    // Some APIs expect a PUT request in the format URL/object/ID
- *    // Here we are creating an 'update' method
- *    app.factory('Notes', ['$resource', function($resource) {
- *    return $resource('/notes/:id', null,
- *        {
- *            'update': { method:'PUT' }
- *        });
- *    }]);
- *
- *    // In our controller we get the ID from the URL using ngRoute and $routeParams
- *    // We pass in $routeParams and our Notes factory along with $scope
- *    app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',
-                                      function($scope, $routeParams, Notes) {
- *    // First get a note object from the factory
- *    var note = Notes.get({ id:$routeParams.id });
- *    $id = note.id;
- *
- *    // Now call update passing in the ID first then the object you are updating
- *    Notes.update({ id:$id }, note);
- *
- *    // This will PUT /notes/ID with the note object in the request payload
- *    }]);
- * ```

-/**
- * @ngdoc service
- * @name $animateCss
- * @kind object
- *
- * @description
- * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
- * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
- * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
- * directives to create more complex animations that can be purely driven using CSS code.
- *
- * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
- * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
- *
- * ## Usage
- * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
- * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
- * any automatic control over cancelling animations and/or preventing animations from being run on
- * child elements will not be handled by Angular. For this to work as expected, please use `$animate` to
- * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
- * the CSS animation.
- *
- * The example below shows how we can create a folding animation on an element using `ng-if`:
- *
- * ```html
- * <!-- notice the `fold-animation` CSS class -->
- * <div ng-if="onOff" class="fold-animation">
- *   This element will go BOOM
- * </div>
- * <button ng-click="onOff=true">Fold In</button>
- * ```
- *
- * Now we create the **JavaScript animation** that will trigger the CSS transition:
- *
- * ```js
- * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
- *   return {
- *     enter: function(element, doneFn) {
- *       var height = element[0].offsetHeight;
- *       return $animateCss(element, {
- *         from: { height:'0px' },
- *         to: { height:height + 'px' },
- *         duration: 1 // one second
- *       });
- *     }
- *   }
- * }]);
- * ```
- *
- * ## More Advanced Uses
- *
- * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
- * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
- *
- * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
- * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
- * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
- * to provide a working animation that will run in CSS.
- *
- * The example below showcases a more advanced version of the `.fold-animation` from the example above:
- *
- * ```js
- * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
- *   return {
- *     enter: function(element, doneFn) {
- *       var height = element[0].offsetHeight;
- *       return $animateCss(element, {
- *         addClass: 'red large-text pulse-twice',
- *         easing: 'ease-out',
- *         from: { height:'0px' },
- *         to: { height:height + 'px' },
- *         duration: 1 // one second
- *       });
- *     }
- *   }
- * }]);
- * ```
- *
- * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
- *
- * ```css
- * /&#42; since a hardcoded duration value of 1 was provided in the JavaScript animation code,
- * the CSS classes below will be transitioned despite them being defined as regular CSS classes &#42;/
- * .red { background:red; }
- * .large-text { font-size:20px; }
- *
- * /&#42; we can also use a keyframe animation and $animateCss will make it work alongside the transition &#42;/
- * .pulse-twice {
- *   animation: 0.5s pulse linear 2;
- *   -webkit-animation: 0.5s pulse linear 2;
- * }
- *
- * @keyframes pulse {
- *   from { transform: scale(0.5); }
- *   to { transform: scale(1.5); }
- * }
- *
- * @-webkit-keyframes pulse {
- *   from { -webkit-transform: scale(0.5); }
- *   to { -webkit-transform: scale(1.5); }
- * }
- * ```
- *
- * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
- *
- * ## How the Options are handled
- *
- * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
- * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
- * styles using the `from` and `to` properties.
- *
- * ```js
- * var animator = $animateCss(element, {
- *   from: { background:'red' },
- *   to: { background:'blue' }
- * });
- * animator.start();
- * ```
- *
- * ```css
- * .rotating-animation {
- *   animation:0.5s rotate linear;
- *   -webkit-animation:0.5s rotate linear;
- * }
- *
- * @keyframes rotate {
- *   from { transform: rotate(0deg); }
- *   to { transform: rotate(360deg); }
- * }
- *
- * @-webkit-keyframes rotate {
- *   from { -webkit-transform: rotate(0deg); }
- *   to { -webkit-transform: rotate(360deg); }
- * }
- * ```
- *
- * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
- * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
- * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
- * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
- * and spread across the transition and keyframe animation.
- *
- * ## What is returned
- *
- * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
- * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
- * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
- *
- * ```js
- * var animator = $animateCss(element, { ... });
- * ```
- *
- * Now what do the contents of our `animator` variable look like:
- *
- * ```js
- * {
- *   // starts the animation
- *   start: Function,
- *
- *   // ends (aborts) the animation
- *   end: Function
- * }
- * ```
- *
- * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
- * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and stlyes may have been
- * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
- * and that changing them will not reconfigure the parameters of the animation.
- *
- * ### runner.done() vs runner.then()
- * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
- * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
- * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
- * unless you really need a digest to kick off afterwards.
- *
- * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
- * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
- * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
- *
- * @param {DOMElement} element the element that will be animated
- * @param {object} options the animation-related options that will be applied during the animation
- *
- * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
- * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
- * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
- * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
- * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
- * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
- * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
- * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
- * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
- * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
- * is provided then the animation will be skipped entirely.
- * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
- * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
- * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
- * CSS delay value.
- * * `stagger` - A numeric time value representing the delay between successively animated elements
- * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
- * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
- * * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
- * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occuring on the classes being added and removed.)
- * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
- *    the animation is closed. This is useful for when the styles are used purely for the sake of
- *    the animation and do not have a lasting visual effect on the element (e.g. a colapse and open animation).
- *    By default this value is set to `false`.
- *
- * @return {object} an object with start and end methods and details about the animation.
- *
- * * `start` - The method to start the animation. This will return a `Promise` when called.
- * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

- * @ngdoc module
- * @name ngAnimate
- * @description
- *
- * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
- * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an Angular app.
- *
- * <div doc-module-components="ngAnimate"></div>
- *
- * # Usage
- * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
- * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
- * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
- * the HTML element that the animation will be triggered on.
- *
- * ## Directive Support
- * The following directives are "animation aware":
- *
- * | Directive                                                                                                | Supported Animations                                                     |
- * |----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------|
- * | {@link ng.directive:ngRepeat#animations ngRepeat}                                                        | enter, leave and move                                                    |
- * | {@link ngRoute.directive:ngView#animations ngView}                                                       | enter and leave                                                          |
- * | {@link ng.directive:ngInclude#animations ngInclude}                                                      | enter and leave                                                          |

- * | {@link ng.directive:ngIf#animations ngIf}                                                                | enter and leave                                                          |
- * | {@link ng.directive:ngClass#animations ngClass}                                                          | add and remove (the CSS class(es) present)                               |
- * | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide}            | add and remove (the ng-hide class value)                                 |
- * | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel}    | add and remove (dirty, pristine, valid, invalid & all other validations) |
- * | {@link module:ngMessages#animations ngMessages}                                                          | add and remove (ng-active & ng-inactive)                                 |
- * | {@link module:ngMessages#animations ngMessage}                                                           | enter and leave                                                          |

- *
- * ## CSS-based Animations
- *
- * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
- * and CSS code we can create an animation that will be picked up by Angular when an the underlying directive performs an operation.
- *
- * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
- *
- * ```html
- * <div ng-if="bool" class="fade">
- *    Fade me in out
- * </div>
- * <button ng-click="bool=true">Fade In!</button>
- * <button ng-click="bool=false">Fade Out!</button>
- * ```
- *
- * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
- *
- * ```css
- * /&#42; The starting CSS styles for the enter animation &#42;/
- * .fade.ng-enter {
- *   transition:0.5s linear all;
- *   opacity:0;
- * }
- *
- * /&#42; The finishing CSS styles for the enter animation &#42;/
- * .fade.ng-enter.ng-enter-active {
- *   opacity:1;
- * }
- * ```
- *
- * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
- * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
- * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
- *
- * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
- *
- * ```css
- * /&#42; now the element will fade out before it is removed from the DOM &#42;/
- * .fade.ng-leave {
- *   transition:0.5s linear all;
- *   opacity:1;
- * }
- * .fade.ng-leave.ng-leave-active {
- *   opacity:0;
- * }
- * ```
- *
- * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
- *
- * ```css
- * /&#42; there is no need to define anything inside of the destination
- * CSS class since the keyframe will take charge of the animation &#42;/
- * .fade.ng-leave {
- *   animation: my_fade_animation 0.5s linear;
- *   -webkit-animation: my_fade_animation 0.5s linear;
- * }
- *
- * @keyframes my_fade_animation {
- *   from { opacity:1; }
- *   to { opacity:0; }
- * }
- *
- * @-webkit-keyframes my_fade_animation {
- *   from { opacity:1; }
- *   to { opacity:0; }
- * }
- * ```
- *
- * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
- *
- * ### CSS Class-based Animations
- *
- * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
- * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
- * and removed.
- *
- * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
- *
- * ```html
- * <div ng-show="bool" class="fade">
- *   Show and hide me
- * </div>
- * <button ng-click="bool=true">Toggle</button>
- *
- * <style>
- * .fade.ng-hide {
- *   transition:0.5s linear all;
- *   opacity:0;
- * }
- * </style>
- * ```
- *
- * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
- * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
- *
- * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
- * with CSS styles.
- *
- * ```html
- * <div ng-class="{on:onOff}" class="highlight">
- *   Highlight this box
- * </div>
- * <button ng-click="onOff=!onOff">Toggle</button>
- *
- * <style>
- * .highlight {
- *   transition:0.5s linear all;
- * }
- * .highlight.on-add {
- *   background:white;
- * }
- * .highlight.on {
- *   background:yellow;
- * }
- * .highlight.on-remove {
- *   background:black;
- * }
- * </style>
- * ```
- *
- * We can also make use of CSS keyframes by placing them within the CSS classes.
- *
- *
- * ### CSS Staggering Animations
- * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
- * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
- * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
- * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
- * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
- *
- * ```css
- * .my-animation.ng-enter {
- *   /&#42; standard transition code &#42;/
- *   transition: 1s linear all;
- *   opacity:0;
- * }
- * .my-animation.ng-enter-stagger {
- *   /&#42; this will have a 100ms delay between each successive leave animation &#42;/
- *   transition-delay: 0.1s;
- *
- *   /&#42; As of 1.4.4, this must always be set: it signals ngAnimate
- *     to not accidentally inherit a delay property from another CSS class &#42;/
- *   transition-duration: 0s;
- * }
- * .my-animation.ng-enter.ng-enter-active {
- *   /&#42; standard transition styles &#42;/
- *   opacity:1;
- * }
- * ```
- *
- * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
- * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
- * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
- * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
- *
- * The following code will issue the **ng-leave-stagger** event on the element provided:
- *
- * ```js
- * var kids = parent.children();
- *
- * $animate.leave(kids[0]); //stagger index=0
- * $animate.leave(kids[1]); //stagger index=1
- * $animate.leave(kids[2]); //stagger index=2
- * $animate.leave(kids[3]); //stagger index=3
- * $animate.leave(kids[4]); //stagger index=4
- *
- * window.requestAnimationFrame(function() {
- *   //stagger has reset itself
- *   $animate.leave(kids[5]); //stagger index=0
- *   $animate.leave(kids[6]); //stagger index=1
- *
- *   $scope.$digest();
- * });
- * ```
- *
- * Stagger animations are currently only supported within CSS-defined animations.
- *
- * ### The `ng-animate` CSS class
- *
- * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
- * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
- *
- * Therefore, animations can be applied to an element using this temporary class directly via CSS.
- *
- * ```css
- * .zipper.ng-animate {
- *   transition:0.5s linear all;
- * }
- * .zipper.ng-enter {
- *   opacity:0;
- * }
- * .zipper.ng-enter.ng-enter-active {
- *   opacity:1;
- * }
- * .zipper.ng-leave {
- *   opacity:1;
- * }
- * .zipper.ng-leave.ng-leave-active {
- *   opacity:0;
- * }
- * ```
- *
- * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
- * the CSS class once an animation has completed.)
- *
- *
- * ## JavaScript-based Animations
- *
- * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
- * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
- * `module.animation()` module function we can register the ainmation.
- *
- * Let's see an example of a enter/leave animation using `ngRepeat`:
- *
- * ```html
- * <div ng-repeat="item in items" class="slide">
- *   {{ item }}
- * </div>
- * ```
- *
- * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
- *
- * ```js
- * myModule.animation('.slide', [function() {
- *   return {
- *     // make note that other events (like addClass/removeClass)
- *     // have different function input parameters
- *     enter: function(element, doneFn) {
- *       jQuery(element).fadeIn(1000, doneFn);
- *
- *       // remember to call doneFn so that angular
- *       // knows that the animation has concluded
- *     },
- *
- *     move: function(element, doneFn) {
- *       jQuery(element).fadeIn(1000, doneFn);
- *     },
- *
- *     leave: function(element, doneFn) {
- *       jQuery(element).fadeOut(1000, doneFn);
- *     }
- *   }
- * }]
- * ```
- *
- * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
- * greensock.js and velocity.js.
- *
- * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
- * our animations inside of the same registered animation, however, the function input arguments are a bit different:
- *
- * ```html
- * <div ng-class="color" class="colorful">
- *   this box is moody
- * </div>
- * <button ng-click="color='red'">Change to red</button>
- * <button ng-click="color='blue'">Change to blue</button>
- * <button ng-click="color='green'">Change to green</button>
- * ```
- *
- * ```js
- * myModule.animation('.colorful', [function() {
- *   return {
- *     addClass: function(element, className, doneFn) {
- *       // do some cool animation and call the doneFn
- *     },
- *     removeClass: function(element, className, doneFn) {
- *       // do some cool animation and call the doneFn
- *     },
- *     setClass: function(element, addedClass, removedClass, doneFn) {
- *       // do some cool animation and call the doneFn
- *     }
- *   }
- * }]
- * ```
- *
- * ## CSS + JS Animations Together
- *
- * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of Angular,
- * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
- * charge of the animation**:
- *
- * ```html
- * <div ng-if="bool" class="slide">
- *   Slide in and out
- * </div>
- * ```
- *
- * ```js
- * myModule.animation('.slide', [function() {
- *   return {
- *     enter: function(element, doneFn) {
- *       jQuery(element).slideIn(1000, doneFn);
- *     }
- *   }
- * }]
- * ```
- *
- * ```css
- * .slide.ng-enter {
- *   transition:0.5s linear all;
- *   transform:translateY(-100px);
- * }
- * .slide.ng-enter.ng-enter-active {
- *   transform:translateY(0);
- * }
- * ```
- *
- * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
- * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
- * our own JS-based animation code:
- *
- * ```js
- * myModule.animation('.slide', ['$animateCss', function($animateCss) {
- *   return {
- *     enter: function(element, doneFn) {
-*        // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
- *       var runner = $animateCss(element, {
- *         event: 'enter',
- *         structural: true
- *       }).start();
-*        runner.done(doneFn);
- *     }
- *   }
- * }]
- * ```
- *
- * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
- *
- * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
- * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
- * data into `$animateCss` directly:
- *
- * ```js
- * myModule.animation('.slide', ['$animateCss', function($animateCss) {
- *   return {
- *     enter: function(element, doneFn) {
- *       var runner = $animateCss(element, {
- *         event: 'enter',
- *         structural: true,
- *         addClass: 'maroon-setting',
- *         from: { height:0 },
- *         to: { height: 200 }
- *       }).start();
- *
- *       runner.done(doneFn);
- *     }
- *   }
- * }]
- * ```
- *
- * Now we can fill in the rest via our transition CSS code:
- *
- * ```css
- * /&#42; the transition tells ngAnimate to make the animation happen &#42;/
- * .slide.ng-enter { transition:0.5s linear all; }
- *
- * /&#42; this extra CSS class will be absorbed into the transition
- * since the $animateCss code is adding the class &#42;/
- * .maroon-setting { background:red; }
- * ```
- *
- * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
- *
- * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
- *
- * ## Animation Anchoring (via `ng-animate-ref`)
- *
- * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
- * structural areas of an application (like views) by pairing up elements using an attribute
- * called `ng-animate-ref`.
- *
- * Let's say for example we have two views that are managed by `ng-view` and we want to show
- * that there is a relationship between two components situated in within these views. By using the
- * `ng-animate-ref` attribute we can identify that the two components are paired together and we
- * can then attach an animation, which is triggered when the view changes.
- *
- * Say for example we have the following template code:
- *
- * ```html
- * <!-- index.html -->
- * <div ng-view class="view-animation">
- * </div>
- *
- * <!-- home.html -->
- * <a href="#/banner-page">
- *   <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
- * </a>
- *
- * <!-- banner-page.html -->
- * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
- * ```
- *
- * Now, when the view changes (once the link is clicked), ngAnimate will examine the
- * HTML contents to see if there is a match reference between any components in the view
- * that is leaving and the view that is entering. It will scan both the view which is being
- * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
- * contain a matching ref value.
- *
- * The two images match since they share the same ref value. ngAnimate will now create a
- * transport element (which is a clone of the first image element) and it will then attempt
- * to animate to the position of the second image element in the next view. For the animation to
- * work a special CSS class called `ng-anchor` will be added to the transported element.
- *
- * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
- * ngAnimate will handle the entire transition for us as well as the addition and removal of
- * any changes of CSS classes between the elements:
- *
- * ```css
- * .banner.ng-anchor {
- *   /&#42; this animation will last for 1 second since there are
- *          two phases to the animation (an `in` and an `out` phase) &#42;/
- *   transition:0.5s linear all;
- * }
- * ```
- *
- * We also **must** include animations for the views that are being entered and removed
- * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
- *
- * ```css
- * .view-animation.ng-enter, .view-animation.ng-leave {
- *   transition:0.5s linear all;
- *   position:fixed;
- *   left:0;
- *   top:0;
- *   width:100%;
- * }
- * .view-animation.ng-enter {
- *   transform:translateX(100%);
- * }
- * .view-animation.ng-leave,
- * .view-animation.ng-enter.ng-enter-active {
- *   transform:translateX(0%);
- * }
- * .view-animation.ng-leave.ng-leave-active {
- *   transform:translateX(-100%);
- * }
- * ```
- *
- * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
- * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
- * from its origin. Once that animation is over then the `in` stage occurs which animates the
- * element to its destination. The reason why there are two animations is to give enough time
- * for the enter animation on the new element to be ready.
- *
- * The example above sets up a transition for both the in and out phases, but we can also target the out or
- * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
- *
- * ```css
- * .banner.ng-anchor-out {
- *   transition: 0.5s linear all;
- *
- *   /&#42; the scale will be applied during the out animation,
- *          but will be animated away when the in animation runs &#42;/
- *   transform: scale(1.2);
- * }
- *
- * .banner.ng-anchor-in {
- *   transition: 1s linear all;
- * }
- * ```
- *
- *
- *
- *

- * ### How is the element transported?
- *
- * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
- * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
- * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
- * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
- * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
- * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
- * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
- * will become visible since the shim class will be removed.
- *
- * ### How is the morphing handled?
- *
- * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
- * what CSS classes differ between the starting element and the destination element. These different CSS classes
- * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
- * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
- * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
- * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
- * the cloned element is placed inside of root element which is likely close to the body element).
- *
- * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
- *
- *
- * ## Using $animate in your directive code
- *
- * So far we've explored how to feed in animations into an Angular application, but how do we trigger animations within our own directives in our application?
- * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
- * imagine we have a greeting box that shows and hides itself when the data changes
- *
- * ```html
- * <greeting-box active="onOrOff">Hi there</greeting-box>
- * ```
- *
- * ```js
- * ngModule.directive('greetingBox', ['$animate', function($animate) {
- *   return function(scope, element, attrs) {
- *     attrs.$observe('active', function(value) {
- *       value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
- *     });
- *   });
- * }]);
- * ```
- *
- * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
- * in our HTML code then we can trigger a CSS or JS animation to happen.
- *
- * ```css
- * /&#42; normally we would create a CSS class to reference on the element &#42;/
- * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
- * ```
- *
- * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
- * possible be sure to visit the {@link ng.$animate $animate service API page}.
- *
- *
- * ### Preventing Collisions With Third Party Libraries
- *
- * Some third-party frameworks place animation duration defaults across many element or className
- * selectors in order to make their code small and reuseable. This can lead to issues with ngAnimate, which
- * is expecting actual animations on these elements and has to wait for their completion.
- *
- * You can prevent this unwanted behavior by using a prefix on all your animation classes:
- *
- * ```css
- * /&#42; prefixed with animate- &#42;/
- * .animate-fade-add.animate-fade-add-active {
- *   transition:1s linear all;
- *   opacity:0;
- * }
- * ```
- *
- * You then configure `$animate` to enforce this prefix:
- *
- * ```js
- * $animateProvider.classNameFilter(/animate-/);
- * ```
- *
- * This also may provide your application with a speed boost since only specific elements containing CSS class prefix
- * will be evaluated for animation when any DOM changes occur in the application.
- *
- * ## Callbacks and Promises
- *
- * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
- * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
- * ended by chaining onto the returned promise that animation method returns.
- *
- * ```js
- * // somewhere within the depths of the directive
- * $animate.enter(element, parent).then(function() {
- *   //the animation has completed
- * });
- * ```
- *
- * (Note that earlier versions of Angular prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
- * anymore.)
- *
- * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
- * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
- * routing controller to hook into that:
- *
- * ```js
- * ngModule.controller('HomePageController', ['$animate', function($animate) {
- *   $animate.on('enter', ngViewElement, function(element) {
- *     // the animation for this route has completed
- *   }]);
- * }])
- * ```
- *
- * (Note that you will need to trigger a digest within the callback to get angular to notice any scope-related changes.)

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array of at least `200` elements
-     * and any iteratees accept only one argument. The heuristic for whether a
-     * section qualifies for shortcut fusion is subject to change.

-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.

-     * Creates a debounced function that delays invoking `func` until after `wait`
-     * milliseconds have elapsed since the last time the debounced function was
-     * invoked. The debounced function comes with a `cancel` method to cancel
-     * delayed `func` invocations and a `flush` method to immediately invoke them.
-     * Provide an options object to indicate whether `func` should be invoked on
-     * the leading and/or trailing edge of the `wait` timeout. The `func` is invoked
-     * with the last arguments provided to the debounced function. Subsequent calls
-     * to the debounced function return the result of the last `func` invocation.
-     *
-     * **Note:** If `leading` and `trailing` options are `true`, `func` is invoked
-     * on the trailing edge of the timeout only if the debounced function is
-     * invoked more than once during the `wait` timeout.

- * @ngdoc module
- * @name ngMessages
- * @description
- *
- * The `ngMessages` module provides enhanced support for displaying messages within templates
- * (typically within forms or when rendering message objects that return key/value data).
- * Instead of relying on JavaScript code and/or complex ng-if statements within your form template to
- * show and hide error messages specific to the state of an input field, the `ngMessages` and
- * `ngMessage` directives are designed to handle the complexity, inheritance and priority
- * sequencing based on the order of how the messages are defined in the template.
- *
- * Currently, the ngMessages module only contains the code for the `ngMessages`, `ngMessagesInclude`
- * `ngMessage` and `ngMessageExp` directives.
- *
- * # Usage
- * The `ngMessages` directive allows keys in a key/value collection to be associated with a child element
- * (or 'message') that will show or hide based on the truthiness of that key's value in the collection. A common use
- * case for `ngMessages` is to display error messages for inputs using the `$error` object exposed by the
- * {@link ngModel ngModel} directive.
- *
- * The child elements of the `ngMessages` directive are matched to the collection keys by a `ngMessage` or
- * `ngMessageExp` directive. The value of these attributes must match a key in the collection that is provided by
- * the `ngMessages` directive.
- *
- * Consider the following example, which illustrates a typical use case of `ngMessages`. Within the form `myForm` we
- * have a text input named `myField` which is bound to the scope variable `field` using the {@link ngModel ngModel}
- * directive.
- *
- * The `myField` field is a required input of type `email` with a maximum length of 15 characters.
- *
- * ```html
- * <form name="myForm">
- *   <label>
- *     Enter text:
- *     <input type="email" ng-model="field" name="myField" required maxlength="15" />
- *   </label>
- *   <div ng-messages="myForm.myField.$error" role="alert">
- *     <div ng-message="required">Please enter a value for this field.</div>
- *     <div ng-message="email">This field must be a valid email address.</div>
- *     <div ng-message="maxlength">This field can be at most 15 characters long.</div>
- *   </div>
- * </form>
- * ```
- *
- * In order to show error messages corresponding to `myField` we first create an element with an `ngMessages` attribute
- * set to the `$error` object owned by the `myField` input in our `myForm` form.
- *
- * Within this element we then create separate elements for each of the possible errors that `myField` could have.
- * The `ngMessage` attribute is used to declare which element(s) will appear for which error - for example,
- * setting `ng-message="required"` specifies that this particular element should be displayed when there
- * is no value present for the required field `myField` (because the key `required` will be `true` in the object
- * `myForm.myField.$error`).
- *
- * ### Message order
- *
- * By default, `ngMessages` will only display one message for a particular key/value collection at any time. If more
- * than one message (or error) key is currently true, then which message is shown is determined by the order of messages
- * in the HTML template code (messages declared first are prioritised). This mechanism means the developer does not have
- * to prioritise messages using custom JavaScript code.
- *
- * Given the following error object for our example (which informs us that the field `myField` currently has both the
- * `required` and `email` errors):
- *
- * ```javascript
- * <!-- keep in mind that ngModel automatically sets these error flags -->
- * myField.$error = { required : true, email: true, maxlength: false };
- * ```
- * The `required` message will be displayed to the user since it appears before the `email` message in the DOM.
- * Once the user types a single character, the `required` message will disappear (since the field now has a value)
- * but the `email` message will be visible because it is still applicable.
- *
- * ### Displaying multiple messages at the same time
- *
- * While `ngMessages` will by default only display one error element at a time, the `ng-messages-multiple` attribute can
- * be applied to the `ngMessages` container element to cause it to display all applicable error messages at once:
- *
- * ```html
- * <!-- attribute-style usage -->
- * <div ng-messages="myForm.myField.$error" ng-messages-multiple>...</div>
- *
- * <!-- element-style usage -->
- * <ng-messages for="myForm.myField.$error" multiple>...</ng-messages>
- * ```
- *
- * ## Reusing and Overriding Messages
- * In addition to prioritization, ngMessages also allows for including messages from a remote or an inline
- * template. This allows for generic collection of messages to be reused across multiple parts of an
- * application.
- *
- * ```html
- * <script type="text/ng-template" id="error-messages">
- *   <div ng-message="required">This field is required</div>
- *   <div ng-message="minlength">This field is too short</div>
- * </script>
- *
- * <div ng-messages="myForm.myField.$error" role="alert">
- *   <div ng-messages-include="error-messages"></div>
- * </div>
- * ```
- *
- * However, including generic messages may not be useful enough to match all input fields, therefore,
- * `ngMessages` provides the ability to override messages defined in the remote template by redefining
- * them within the directive container.
- *
- * ```html
- * <!-- a generic template of error messages known as "my-custom-messages" -->
- * <script type="text/ng-template" id="my-custom-messages">
- *   <div ng-message="required">This field is required</div>
- *   <div ng-message="minlength">This field is too short</div>
- * </script>
- *
- * <form name="myForm">
- *   <label>
- *     Email address
- *     <input type="email"
- *            id="email"
- *            name="myEmail"
- *            ng-model="email"
- *            minlength="5"
- *            required />
- *   </label>
- *   <!-- any ng-message elements that appear BEFORE the ng-messages-include will
- *        override the messages present in the ng-messages-include template -->
- *   <div ng-messages="myForm.myEmail.$error" role="alert">
- *     <!-- this required message has overridden the template message -->
- *     <div ng-message="required">You did not enter your email address</div>
- *
- *     <!-- this is a brand new message and will appear last in the prioritization -->
- *     <div ng-message="email">Your email address is invalid</div>
- *
- *     <!-- and here are the generic error messages -->
- *     <div ng-messages-include="my-custom-messages"></div>
- *   </div>
- * </form>
- * ```
- *
- * In the example HTML code above the message that is set on required will override the corresponding
- * required message defined within the remote template. Therefore, with particular input fields (such
- * email addresses, date fields, autocomplete inputs, etc...), specialized error messages can be applied
- * while more generic messages can be used to handle other, more general input errors.
- *
- * ## Dynamic Messaging
- * ngMessages also supports using expressions to dynamically change key values. Using arrays and
- * repeaters to list messages is also supported. This means that the code below will be able to
- * fully adapt itself and display the appropriate message when any of the expression data changes:
- *
- * ```html
- * <form name="myForm">
- *   <label>
- *     Email address
- *     <input type="email"
- *            name="myEmail"
- *            ng-model="email"
- *            minlength="5"
- *            required />
- *   </label>
- *   <div ng-messages="myForm.myEmail.$error" role="alert">
- *     <div ng-message="required">You did not enter your email address</div>
- *     <div ng-repeat="errorMessage in errorMessages">
- *       <!-- use ng-message-exp for a message whose key is given by an expression -->
- *       <div ng-message-exp="errorMessage.type">{{ errorMessage.text }}</div>
- *     </div>
- *   </div>
- * </form>
- * ```
- *
- * The `errorMessage.type` expression can be a string value or it can be an array so
- * that multiple errors can be associated with a single error message:
- *
- * ```html
- *   <label>
- *     Email address
- *     <input type="email"
- *            ng-model="data.email"
- *            name="myEmail"
- *            ng-minlength="5"
- *            ng-maxlength="100"
- *            required />
- *   </label>
- *   <div ng-messages="myForm.myEmail.$error" role="alert">
- *     <div ng-message-exp="'required'">You did not enter your email address</div>
- *     <div ng-message-exp="['minlength', 'maxlength']">
- *       Your email must be between 5 and 100 characters long
- *     </div>
- *   </div>
- * ```
- *
- * Feel free to use other structural directives such as ng-if and ng-switch to further control
- * what messages are active and when. Be careful, if you place ng-message on the same element
- * as these structural directives, Angular may not be able to determine if a message is active
- * or not. Therefore it is best to place the ng-message on a child element of the structural
- * directive.
- *
- * ```html
- * <div ng-messages="myForm.myEmail.$error" role="alert">
- *   <div ng-if="showRequiredError">
- *     <div ng-message="required">Please enter something</div>
- *   </div>
- * </div>
- * ```
- *
- * ## Animations
- * If the `ngAnimate` module is active within the application then the `ngMessages`, `ngMessage` and
- * `ngMessageExp` directives will trigger animations whenever any messages are added and removed from
- * the DOM by the `ngMessages` directive.
- *
- * Whenever the `ngMessages` directive contains one or more visible messages then the `.ng-active` CSS
- * class will be added to the element. The `.ng-inactive` CSS class will be applied when there are no
- * messages present. Therefore, CSS transitions and keyframes as well as JavaScript animations can
- * hook into the animations whenever these classes are added/removed.
- *
- * Let's say that our HTML code for our messages container looks like so:
- *
- * ```html
- * <div ng-messages="myMessages" class="my-messages" role="alert">
- *   <div ng-message="alert" class="some-message">...</div>
- *   <div ng-message="fail" class="some-message">...</div>
- * </div>
- * ```
- *
- * Then the CSS animation code for the message container looks like so:
- *
- * ```css
- * .my-messages {
- *   transition:1s linear all;
- * }
- * .my-messages.ng-active {
- *   // messages are visible
- * }
- * .my-messages.ng-inactive {
- *   // messages are hidden
- * }
- * ```
- *
- * Whenever an inner message is attached (becomes visible) or removed (becomes hidden) then the enter
- * and leave animation is triggered for each particular element bound to the `ngMessage` directive.
- *
- * Therefore, the CSS code for the inner messages looks like so:
- *
- * ```css
- * .some-message {
- *   transition:1s linear all;
- * }
- *
- * .some-message.ng-enter {}
- * .some-message.ng-enter.ng-enter-active {}
- *
- * .some-message.ng-leave {}
- * .some-message.ng-leave.ng-leave-active {}
- * ```

-    *
-    * @description
-    * `ngMessages` is a directive that is designed to show and hide messages based on the state
-    * of a key/value object that it listens on. The directive itself complements error message
-    * reporting with the `ngModel` $error object (which stores a key/value state of validation errors).
-    *
-    * `ngMessages` manages the state of internal messages within its container element. The internal
-    * messages use the `ngMessage` directive and will be inserted/removed from the page depending
-    * on if they're present within the key/value object. By default, only one message will be displayed
-    * at a time and this depends on the prioritization of the messages within the template. (This can
-    * be changed by using the `ng-messages-multiple` or `multiple` attribute on the directive container.)
-    *
-    * A remote template can also be used to promote message reusability and messages can also be
-    * overridden.

-			 * Right, this is really confusing and there is a lot of maths going on here
-			 * The gist of the problem is here: https://gist.github.com/nnnick/696cc9c55f4b0beb8fe9
-			 *
-			 * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
-			 *
-			 * Solution:
-			 *
-			 * We assume the radius of the polygon is half the size of the canvas at first
-			 * at each index we check if the text overlaps.
-			 *
-			 * Where it does, we store that angle and that index.
-			 *
-			 * After finding the largest index and angle we calculate how much we need to remove
-			 * from the shape radius to move the point inwards by that x.
-			 *
-			 * We average the left and right distances to get the maximum shape radius that can fit in the box
-			 * along with labels.
-			 *
-			 * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
-			 * on each side, removing that from the size, halving it and adding the left x protrusion width.
-			 *
-			 * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
-			 * and position it in the most space efficient manner
-			 *
