/**
 * @ngdoc service
 * @name $mdBottomSheet
 * @module material.components.bottomSheet
 *
 * @description
 * `$mdBottomSheet` opens a bottom sheet over the app and provides a simple promise API.
 *
 * ## Restrictions
 *
 * - The bottom sheet's template must have an outer `<md-bottom-sheet>` element.
 * - Add the `md-grid` class to the bottom sheet for a grid layout.
 * - Add the `md-list` class to the bottom sheet for a list layout.
 *
 * @usage
 * <hljs lang="html">
 * <div ng-controller="MyController">
 *   <md-button ng-click="openBottomSheet()">
 *     Open a Bottom Sheet!
 *   </md-button>
 * </div>
 * </hljs>
 * <hljs lang="js">
 * var app = angular.module('app', ['ngMaterial']);
 * app.controller('MyController', function($scope, $mdBottomSheet) {
 *   $scope.openBottomSheet = function() {
 *     $mdBottomSheet.show({
 *       template: '<md-bottom-sheet>' +
 *       'Hello! <md-button ng-click="closeBottomSheet()">Close</md-button>' +
 *       '</md-bottom-sheet>'
 *     })
 *
 *     // Fires when the hide() method is used
 *     .then(function() {
 *       console.log('You clicked the button to close the bottom sheet!');
 *     })
 *
 *     // Fires when the cancel() method is used
 *     .catch(function() {
 *       console.log('You hit escape or clicked the backdrop to close.');
 *     });
 *   };
 *
 *   $scope.closeBottomSheet = function($scope, $mdBottomSheet) {
 *     $mdBottomSheet.hide();
 *   }
 *
 * });
 * </hljs>
 *
 * ### 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">
 *   $mdBottomSheetProvider.addPreset('testPreset', {
 *     options: function() {
 *       return {
 *         template:
 *           '<md-bottom-sheet>' +
 *             'This is a custom preset' +
 *           '</md-bottom-sheet>',
 *         controllerAs: 'bottomSheet',
 *         bindToController: true,
 *         clickOutsideToClose: true,
 *         escapeToClose: true
 *       };
 *     }
 *   });
 * </hljs>
 *
 * After you create your preset during the config phase, you can easily access it.
 *
 * <hljs lang="js">
 *   $mdBottomSheet.show(
 *     $mdBottomSheet.testPreset()
 *   );
 * </hljs>

 /**
 * @ngdoc method
 * @name $mdBottomSheet#show
 *
 * @description
 * Show a bottom sheet with the specified options.
 *
 * <em><b>Note:</b> You should <b>always</b> provide a `.catch()` method in case the user hits the
 * `esc` key or clicks the background to close. In this case, the `cancel()` method will
 * automatically be called on the bottom sheet which will `reject()` the promise. See the @usage
 * section above for an example.
 *
 * Newer versions of Angular will throw a `Possibly unhandled rejection` exception if you forget
 * this.</em>
 *
 * @param {object} optionsOrPreset Either provide an `$mdBottomSheetPreset` defined during the config phase or
 * an options object, with the following properties:
 *
 *   - `templateUrl` - `{string=}`: The url of an html template file that will
 *   be used as the content of the bottom sheet. Restrictions: the template must
 *   have an outer `md-bottom-sheet` element.
 *   - `template` - `{string=}`: Same as templateUrl, except this is an actual
 *   template string.
 *   - `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 bottom sheet is removed unless `preserveScope` is set to true.
 *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
 *   - `controller` - `{string=}`: The controller to associate with this bottom sheet.
 *   - `locals` - `{string=}`: 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.
 *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click outside the bottom sheet to
 *     close it. Default true.
 *   - `bindToController` - `{boolean=}`: When set to true, the locals will be bound to the controller instance.
 *   - `disableBackdrop` - `{boolean=}`: When set to true, the bottomsheet will not show a backdrop.
 *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to close the bottom sheet.
 *     Default true.
 *   - `isLockedOpen` - `{boolean=}`: Disables all default ways of closing the bottom sheet. **Note:** this will override
 *     the `clickOutsideToClose` and `escapeToClose` options, leaving only the `hide` and `cancel`
 *     methods as ways of closing the bottom sheet. Defaults to false.
 *   - `resolve` - `{object=}`: Similar to locals, except it takes promises as values
 *   and the bottom sheet 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 bottom sheet to. The `parent` may be a `function`, `string`,
 *   `object`, or null. Defaults to appending to the body of the root element (or the root element) of the application.
 *   e.g. angular.element(document.getElementById('content')) or "#content"
 *   - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the bottom sheet is open.
 *     Default true.
 *
 * @returns {promise} A promise that can be resolved with `$mdBottomSheet.hide()` or
 * rejected with `$mdBottomSheet.cancel()`.
