     * @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 prioritize 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.
