// class description:
//     This class extends G4UserTrackingAction and allows multiple
//     user-defined tracking actions to be used in the same job.
//     The class is a vector of user-defined tracking actions.
//     This class owns and manages the dependent user-actions.
// Usage:
//     There is no need to explicitly use this class as long as the
//     user actions are set via G4UserActionInitialization::SetUserAction
//     that can be called several times. Explicitly this is what is happening:
//     In user-defined action initialization:
//      G4MultiTrackingAction* action = new G4MultiTrackingAction;
//      action->push_back( G4UserTrackingActionUPtr( new MyUserTrackingAction );
//      [... add as many as needed ...]
//      SetUserAction( action );
