/**
 * @ngdoc service
 * @name $mdToast
 * @module material.components.toast
 *
 * @description
 * `$mdToast` is a service to build a toast notification on any position
 * on the screen with an optional duration, and provides a simple promise API.
 *
 * The toast will be always positioned at the `bottom`, when the screen size is
 * between `600px` and `959px` (`sm` breakpoint)
 *
 * ## Restrictions on custom toasts
 * - The toast's template must have an outer `<md-toast>` element.
 * - For a toast action, use element with class `md-action`.
 * - Add the class `md-capsule` for curved corners.
 *
 * ### Custom Presets
 * Developers are also able to create their own preset, which can be easily used without repeating
 * their options each time.
 *
 * <hljs lang="js">
 *   $mdToastProvider.addPreset('testPreset', {
 *     options: function() {
 *       return {
 *         template:
 *           '<md-toast>' +
 *             '<div class="md-toast-content">' +
 *               'This is a custom preset' +
 *             '</div>' +
 *           '</md-toast>',
 *         controllerAs: 'toast',
 *         bindToController: true
 *       };
 *     }
 *   });
 * </hljs>
 *
 * After you created your preset at config phase, you can easily access it.
 *
 * <hljs lang="js">
 *   $mdToast.show(
 *     $mdToast.testPreset()
 *   );
 * </hljs>
 *
 * ## Parent container notes
 *
 * The toast is positioned using absolute positioning relative to its first non-static parent
 * container. Thus, if the requested parent container uses static positioning, we will temporarily
 * set its positioning to `relative` while the toast is visible and reset it when the toast is
 * hidden.
 *
 * Because of this, it is usually best to ensure that the parent container has a fixed height and
 * prevents scrolling by setting the `overflow: hidden;` style. Since the position is based off of
 * the parent's height, the toast may be mispositioned if you allow the parent to scroll.
 *
 * You can, however, have a scrollable element inside of the container; just make sure the
 * container itself does not scroll.
 *
 * <hljs lang="html">
 * <div layout-fill id="toast-container">
 *   <md-content>
 *     I can have lots of content and scroll!
 *   </md-content>
 * </div>
 * </hljs>
 *
 * @usage
 * <hljs lang="html">
 * <div ng-controller="MyController">
 *   <md-button ng-click="openToast()">
 *     Open a Toast!
 *   </md-button>
 * </div>
 * </hljs>
 *
 * <hljs lang="js">
 * var app = angular.module('app', ['ngMaterial']);
 * app.controller('MyController', function($scope, $mdToast) {
 *   $scope.openToast = function($event) {
 *     $mdToast.show($mdToast.simple().textContent('Hello!'));

 *
 * @param {Object} optionsOrPreset Either provide an `$mdToastPreset` returned from `simple()`

 *
 *   - `templateUrl` - `{string=}`: The url of an html template file that will
 *     be used as the content of the toast. Restrictions: the template must
 *     have an outer `md-toast` element.
 *   - `template` - `{string=}`: Same as templateUrl, except this is an actual
 *     template string.
 *   - `autoWrap` - `{boolean=}`: Whether or not to automatically wrap the template content with a
 *     `<div class="md-toast-content">` if one is not provided. Defaults to true. Can be disabled
 *     if you provide a custom toast directive.
 *   - `scope` - `{Object=}`: the scope to link the template / controller to. If none is specified,
 *     it will create a new child scope. This scope will be destroyed when the toast is removed
 *     unless `preserveScope` is set to true.
 *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed.
 *     Default is false
 *   - `hideDelay` - `{number=}`: The number of milliseconds the toast should stay active before
 *     automatically closing. Set to `0` or `false` to have the toast stay open until closed
 *     manually via an action in the toast, a hotkey, or a swipe gesture. For accessibility, toasts
 *     should not automatically close when they contain an action.<br>
 *     Defaults to: `3000`.
 *   - `position` - `{string=}`: Sets the position of the toast. <br/>
 *     Available: any combination of `'bottom'`, `'left'`, `'top'`, `'right'`, `'end'`, and
 *     `'start'`. The properties `'end'` and `'start'` are dynamic and can be used for RTL support.
 *     <br/>
 *     Default combination: `'bottom left'`.
 *   - `toastClass` - `{string=}`: A class to set on the toast element.
 *   - `controller` - `{string=}`: The controller to associate with this toast.
 *     The controller will be injected the local `$mdToast.hide()`, which is a function
 *     used to hide the toast.
 *   - `locals` - `{Object=}`: An object containing key/value pairs. The keys will be used as names
 *     of values to inject into the controller. For example, `locals: {three: 3}` would inject
 *     `three` into the controller with the value of 3.
 *   - `bindToController` - `{boolean=}`: bind the locals to the controller, instead of passing
 *     them in.
 *   - `resolve` - `{Object=}`: Similar to locals, except it takes promises as values
 *     and the toast will not open until the promises resolve.
 *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
 *   - `parent` - `{element=}`: The element to append the toast to. Defaults to appending
 *     to the root element of the application.
 *
 * @returns {promise} A promise that can be resolved with `$mdToast.hide()`. `$mdToast.hide()` will
 * resolve either with the boolean value `true` or the value passed as an argument to
 * `$mdToast.hide()`.
