+ * @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 listens on a key/value collection which is set on the ngMessages attribute.
+ * Since the {@link ngModel ngModel} directive exposes an `$error` object, this error object can be
+ * used with `ngMessages` to display control error messages in an easier way than with just regular angular
+ * template directives.
+ *
+ * ```html
+ * <form name="myForm">
+ * <label>
+ * Enter text:
+ * <input type="text" ng-model="field" name="myField" required minlength="5" />
+ * </label>
+ * <div ng-messages="myForm.myField.$error" role="alert">
+ * <div ng-message="required">You did not enter a field</div>
+ * <div ng-message="minlength, maxlength">
+ * Your email must be between 5 and 100 characters long
+ * </div>
+ * </div>
+ * </form>
+ * ```
+ *
+ * Now whatever key/value entries are present within the provided object (in this case `$error`) then
+ * the ngMessages directive will render the inner first ngMessage directive (depending if the key values
+ * match the attribute value present on each ngMessage directive). In other words, if your errors
+ * object contains the following data:
+ *
+ * ```javascript
+ * <!-- keep in mind that ngModel automatically sets these error flags -->
+ * myField.$error = { minlength : true, required : true };
+ * ```
+ *
+ * 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
+ * <!-- 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 {}
+ * ```
