/**
 * @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`
 * and `ngMessage` directives.
 *
 * # Usage
 * The `ngMessages` directive listens on a key/value collection which is set on the ngMessages attribute.
 * Since the {@link ngModel ngModel} directive exposes an `$error` object, this error object can be
 * used with `ngMessages` to display control error messages in an easier way than with just regular angular
 * template directives.
 *
 * ```html
 * <form name="myForm">
 *   <input type="text" ng-model="field" name="myField" required minlength="5" />
 *   <div ng-messages="myForm.myField.$error">
 *     <div ng-message="required">You did not enter a field</div>
 *     <div ng-message="minlength">The value entered is too short</div>
 *   </div>
 * </form>
 * ```
 *
 * Now whatever key/value entries are present within the provided object (in this case `$error`) then
 * the ngMessages directive will render the inner first ngMessage directive (depending if the key values
 * match the attribute value present on each ngMessage directive). In other words, if your errors
 * object contains the following data:
 *
 * ```javascript
 * 
 * myField.$error = { minlength : true, required : false };
 * ```
 *
 * Then the `required` message will be displayed first. When required is false then the `minlength` message
 * will be displayed right after (since these messages are ordered this way in the template HTML code).
 * The prioritization of each message is determined by what order they're present in the DOM.
 * Therefore, instead of having custom JavaScript code determine the priority of what errors are
 * present before others, the presentation of the errors are handled within the template.
 *
 * By default, ngMessages will only display one error at a time. However, if you wish to display all
 * messages then the `ng-messages-multiple` attribute flag can be used on the element containing the
 * ngMessages directive to make this happen.
 *
 * ```html
 * <div ng-messages="myForm.myField.$error" ng-messages-multiple>...</div>
 * ```
 *
 * ## Reusing and Overriding Messages
 * In addition to prioritization, ngMessages also allows for including messages from a remote or an inline
 * template. This allows for generic collection of messages to be reused across multiple parts of an
 * application.
 *
 * ```html
 * <script type="text/ng-template" id="error-messages">
 *   <div ng-message="required">This field is required</div>
 *   <div ng-message="minlength">This field is too short</div>
 * </script>
 * <div ng-messages="myForm.myField.$error" ng-messages-include="error-messages"></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
 * then within the directive container.
 *
 * ```html
 * 
 * <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">
 *   <input type="email"
 *          id="email"
 *          name="myEmail"
 *          ng-model="email"
 *          minlength="5"
 *          required />
 *
 *   <div ng-messages="myForm.myEmail.$error" ng-messages-include="my-custom-messages">
 *     
 *     <div ng-message="required">You did not enter your email address</div>
 *
 *     
 *     <div ng-message="email">Your email address is invalid</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.
 *
 * ## Animations
 * If the `ngAnimate` module is active within the application then both the `ngMessages` and
 * `ngMessage` 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
 * animations 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">
 *   <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 compliments 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 on the directive container.)
    *
    * A remote template can also be used to promote message reuseability and messages can also be
    * overridden.
