     * This class is the simple default id generator for Model instances.
     *
     * An example of a configured simple generator would be:
     *
     *     Ext.define('MyApp.data.MyModel', {
     *         extend: 'Ext.data.Model',
     *         config: {
     *             identifier: {
     *                 type: 'simple',
     *                 prefix: 'ID_'
     *             }
     *         }
     *     });
     *     // assign id's of ID_1, ID_2, ID_3, etc.
     *
