// 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; it 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 happens:
//   In user-defined action initialization:
//     G4MultiTrackingAction* action = new G4MultiTrackingAction;
//     action->push_back( G4UserTrackingActionUPtr( new MyUserTrackingAction );
//       [... add as many as needed ...]
//     SetUserAction( action );
