 * @param   CliOutput            $output      The output handler.
 * @param   CliInput             $cliInput    The CLI input handler.
 * @param   DispatcherInterface  $dispatcher  An optional argument to provide dependency injection for the application's
 *                                            event dispatcher.  If the argument is a DispatcherInterface object that object will become
 *                                            the application's event dispatcher, if it is null then the default event dispatcher
 *                                            will be created based on the application's loadDispatcher() method.
