// G4MultiEventAction
//
// Class description:
//
// This class extends G4UserEventAction 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:
// G4MultiEventAction* action = new G4MultiEventAction;
// action->push_back( G4UserEventActionUPtr( new MyUserEventAction );
// [... add as many as needed ...]
// SetUserAction( action );
