+// Package log provides a structured Logger interface implemented using zap logger. It provides the following capabilities:
+// 1. Package level logging - a go package can register itself (AddPackage) and have a logger created for that package.
+// 2. Dynamic log level change - for all registered packages (SetAllLogLevel)
+// 3. Dynamic log level change - for a given package (SetPackageLogLevel)
+// 4. Provides a default logger for unregistered packages (however avoid its usage)
+// 5. Allow key-value pairs to be added to a logger(UpdateLogger) or all loggers (UpdateAllLoggers) at run time
+// 6. Add to the log output the location where the log was invoked (filename.functionname.linenumber)
+//
+// Using package-level logging (recommended approach). In the examples below, log refers to this log package.
+//
+// 1. In the appropriate package, add the following in the init section of the package (usually in a common.go file)
+// The log level can be changed and any number of default fields can be added as well. The log level specifies
+// the lowest log level that will be in the output while the fields will be automatically added to all log printouts.
+// However, as voltha components re-initialize the log level of each registered package to default initial loglevel
+// passed as CLI argument, the log level passed in RegisterPackage call effectively has no effect.
+//
+// var logger log.CLogger
+// func init() {
+// logger, err = log.RegisterPackage(log.JSON, log.ErrorLevel, log.Fields{"key1": "value1"})
+// }
+//
+// 2. In the calling package, use any of the publicly available functions of local package-level logger instance created
+// in previous step. Here is an example to write an Info log with additional fields:
+//
+// logger.Infow("An example", mylog.Fields{"myStringOutput": "output", "myIntOutput": 2})
+//
+// 3. To dynamically change the log level, you can use
+// a) SetLogLevel from inside your package or
+// b) SetPackageLogLevel from anywhere or
+// c) SetAllLogLevel from anywhere.
+//
+// Dynamic Loglevel configuration feature also uses SetPackageLogLevel method based on triggers received due to
+// Changes to configured loglevels
