// class description:
//
//      This is a class for run control in GEANT4 for multi-threaded runs
// It extends G4RunManager re-implementing multi-threaded behavior in
// key methods. See documentation for G4RunManager
// User should never initialize instances of this class, that are usually handled
// by G4MTRunManager.
// There exists one instance of this class for each worker in a MT application.
