 * A simple class used to mask any {@link Ext.Container}.

 *     // Create our container
 *     var container = Ext.create('Ext.Container', {
 *         html: 'My container!'
 *     });
 *
 *     // Add the container to the Viewport
 *     Ext.Viewport.add(container);
 *
 *     // Mask the container
 *     container.setMasked(true);
