/**
* Notification class. Notifications are used to display short messages to the user. They might be used to show the result of
* asynchronous actions or information about changes in the editor content. It is recommended to use them instead of
* alert dialogs. They should **not** be used if a user response is required nor with dialog windows (e.g. in dialog validation).
*
* There are four types of notifications available, see the {@link #type} property.
*
* Note that the notification constructor only creates a notification instance. To show it, use the {@link #show} method:
*
* var notification = new CKEDITOR.plugins.notification( editor, { message: 'Foo' } );
* notification.show();
*
* You can also use the {@link CKEDITOR.editor#showNotification} method:
*
* editor.showNotification( 'Foo' );
*
* All of the notification actions: ({@link #show}, {@link #update} and {@link #hide}) fire cancelable events
* on the related {@link CKEDITOR.editor} instance so you can integrate editor notifications with your website notifications.
*
* Refer to the [Notifications](http://docs.ckeditor.com/#!/guide/dev_notifications) article for more information about this feature.
