 *
 * Description: An instance of this class is the Application View object for
 *              the DBMS example application.
 *
 *              The view simply shows empty screen. The Avkon GUI is just a
 *              simple tester of the database engine CDBMSDb in
 *              DBEngine.h. There is no functionality for the view, since
 *              all GUI actions relate to menu commands (see AppUi).
