 *     Utility methods to create different kinds of notifications. There are three methods available:
 *
 *     * `ons.notification.alert()`
 *     * `ons.notification.confirm()`
 *     * `ons.notification.prompt()`
 *     * `ons.notification.toast()`
 *
 *     It will automatically display a Material Design dialog on Android devices.
 *   [/en]
 *   [ja]いくつかの種類のアラートダイアログを作成するためのユーティリティメソッドを収めたオブジェクトです。[/ja]
 * @example
 * ons.notification.alert('Hello, world!');
 *
 * ons.notification.confirm('Are you ready?')
 *   .then(
 *     function(answer) {
 *       if (answer === 1) {
 *         ons.notification.alert('Let\'s go!');
 *       }
 *     }
 *   );
 *
 * ons.notification.prompt('How old are ?')
 *   .then(
 *     function(age) {
 *       ons.notification.alert('You are ' + age + ' years old.');
 *     }
