//      This is a class for run control in GEANT4
//
//     For the sequential mode of Geant4 application,
//     user must provide his own classes derived from the following
//     three abstract classes and register them to the RunManager.
//        G4VUserDetectorConstruction       - Detector Geometry, Materials
//        G4VUserPhysicsList                - Particle types and Processes
//        G4VUserPrimaryGeneratorAction     - Event Generator selection
//
//     In addition to the above mandatory classes, user can easily
//     customize of the default functionality of GEANT4 simulation
//     by making his own classes derived from the following 5 user
//     action classes.
//         G4UserRunAction                   - Actions for each Run
//         G4UserEventAction                 - Actions for each Event
//         G4UserStackingAction              - Tracks Stacking selection
//         G4UserTrackingAction              - Actions for each Track
//         G4UserSteppingAction              - Actions for each Step
//
//     User may use G4VUserActionInitialization class to instantiate
//     any of the six user action classes (1 mandatory + 6 optional).
//     In this case, user's concrete G4VUserActionInitialization should
//     be defined to RunManager.
//
//     For the multi-threaed mode of Geant4 application,
//     user must provide his own classes derived from the following
//     two abstract classes and register them to the MTRunManager.
//        G4VUserDetectorConstruction       - Detector Geometry, Materials
//        G4VUserPhysicsList                - Particle types and Processes
//     In addition, user may optionally specify the following.
//        G4UserWorkerInitialization       - Defining thread-local actions
//        G4UserRunAction                   - Actions for entire Run
//
//     For the multi-threaded mode, use of G4VUserActionInitialization
//     is mandatory.
//     In G4VUserActionInitialization, the user has to specify
//     G4VUserPrimaryGeneratorAction class. In addition user may
//     customize of the default functionality of GEANT4 simulation
//     by making his own classes derived from the following 5 user
//     action classes.
//        G4VUserPrimaryGeneratorAction     - Event Generator selection
//        G4UserRunAction                   - Actions for each tread-local Run
//        G4UserEventAction                 - Actions for each Event
//        G4UserStackingAction              - Tracks Stacking selection
//        G4UserTrackingAction              - Actions for each Track
//        G4UserSteppingAction              - Actions for each Step
//
//     G4RunManager is the only manager class in Geant4 kernel which
//     the user MUST construct an object by him/herself in the main()
//     for sequential mode of Geant4 application.
//
//     In the multi-threaded mode, G4MTRunManager is the dedicated
//     run manager which the user MUST construct an object by him/herself
//     in the main().
//
//      Note) G4WorkerRunManager is the run manager for individual
//      thread, and is instantiated automatically, and the user needs
//      not to take care of instantiating/deleting it.
//
//     Also, G4RunManager is the only manager class in Geant4 kernel
//     which the user CAN derive it to costomize the behavior of the
//     run control. For this case, user should use protected methods
//     provided in this class for procedures he/she does not want to
//     change.
//
//     G4RunManager or the derived class of it MUST be a singleton.
//     The user MUST NOT construct more than one object even if there
//     are two different concrete implementations.
//
//     G4RunManager controls all of state changes. See G4ApplicationState.hh
//     in intercoms category for the meanings of each state.
