/**
* @workInProgress
* @ngdoc overview
* @name angular.formatter
* @description
*
* Formatters are used for translating data formats between those used for display and those used
* for storage.
*
* Following is the list of built-in angular formatters:
*
* * {@link angular.formatter.boolean boolean} - Formats user input in boolean format
* * {@link angular.formatter.json json} - Formats user input in JSON format
* * {@link angular.formatter.list list} - Formats user input string as an array
* * {@link angular.formatter.number number} - Formats user input strings as a number
* * {@link angular.formatter.trim trim} - Trims extras spaces from end of user input
*
* For more information about how angular formatters work, and how to create your own formatters,
* see {@link guide/dev_guide.templates.formatters Understanding Angular Formatters} in the angular
* Developer Guide.
