/**
 * @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.
 * @returns {function(string, string, ...): Error} instance

 * Determines if two objects or two values are equivalent. Supports value types, regular
 * expressions, arrays and objects.
 *
 * Two objects or values are considered equivalent if at least one of the following is true:
 *
 * * Both objects or values pass `===` comparison.
 * * Both objects or values are of the same type and all of their properties are equal by
 *   comparing them with `angular.equals`.
 * * Both values are NaN. (In JavaScript, NaN == NaN => false. But we consider two NaN as equal)
 * * Both values represent the same regular expression (In JavasScript,
 *   /abc/ == /abc/ => false. But we consider two regular expressions as equal when their textual
 *   representation matches).
 *
 * During a property comparison, properties of `function` type and properties with names
 * that begin with `$` are ignored.
 *
 * Scope and DOMWindow objects are being compared only by identify (`===`).
 *
 * @param {*} o1 Object or value to compare.
 * @param {*} o2 Object or value to compare.
 * @returns {boolean} True if arguments are equal.

 * @ngdoc directive
 * @name ng.directive:ngApp
 *
 * @element ANY
 * @param {angular.Module} ngApp an optional application
 *   {@link angular.module module} name to load.
 *
 * @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.$injector} when the application is bootstrapped and
 * should contain the application code needed or have dependencies on other modules that will
 * contain the code. See {@link angular.module} for more information.
 *
 * In the example below if the `ngApp` directive were not placed on the `html` element then the
 * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
 * would not be resolved to `3`.
 *
 * `ngApp` is the easiest, and most common, way to bootstrap an application.
 *
 <example module="ngAppDemo">
   <file name="index.html">
   <div ng-controller="ngAppDemoController">
     I can add: {{a}} + {{b}} =  {{ a+b }}
   </file>
   <file name="script.js">
   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
     $scope.a = 1;
     $scope.b = 2;
   });
   </file>

     *
     *
     * # Module
     *
     * A module is a collection of services, directives, filters, and configuration information.
     * `angular.module` is used to configure the {@link AUTO.$injector $injector}.
     *
     * <pre>
     * // Create a new module

     *   // Configure existing providers
     *   $locationProvider.hashPrefix('!');
     * });
     * </pre>

     *
     * <pre>
     * var injector = angular.injector(['ng', 'MyModule'])
     * </pre>
     *
     * However it's more likely that you'll just use
     * {@link ng.directive:ngApp ngApp} or
     * {@link angular.bootstrap} to simplify this process for you.

     * @param {Function} configFn Optional configuration function for the module. Same as
