//	GEANT 4 class header file 
// Class Description:
//      This class is an derived class of G4VUserPhysicsList.     
//       User should regsiter his/her physics constructors 
//      by using 
//         G4VModularPhysicsList::RegsiterPhysics() 
//      to construt particles and processes.
//       In addition User must implement following four virtual methods
//      in his own concrete class derived from this class. 
//        G4VModularPhysicsList::SetCuts()
//           set cut values in range to all particles
//           (and rebuilding physics table will be invoked )
//

//	History
//        first version                   12 Nov. 2000 by H.Kurashige
