// 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.
