-// and consists of three components:
-// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
-// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
-// may apply to the same or different entries in the database. All tests in the guard are applied and
-// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
-// it executes f op (see item 3 below).
-// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
-// lookup operation, and applies to a single database entry. Two different operations in the list may apply
-// to the same or different entries in the database. These operations are executed
-// if guard evaluates to
-// true.
-// 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.

-// to the same or different entries in the database. These operations are executed
