// (Description)
//   This is a primitive scorer class for scoring Surface Current.
//  Current version assumes only for G4Tubs shape, and the surface
//  is defined at the inner plane of the tubs.
//   The current is given in the unit of area. 
//    e.g.  (Number of tracks)/mm2.
//
// Surface is defined at the  inner surface of the tube. 
// Direction                   R    R+dR
