// Class description:
//
// This class is to be used for MT mode.
// Register a particular thread-local G4UImanager with a UI command
// directory name. When a UI command is issued in the master thread
// that starts with this registered directory name, it is immediately
// forwarded to the registered G4UImanager. Such forwarded command
// is not processed in the master thread nor by other worker thread
