// (Description)
//   This is a primitive scorer class for scoring Surface Current.
//  Current version assumes only for G4Box shape, and the surface
//  is defined at the -Z plane of the box.
//   The current is given in the unit of area.
//    e.g.  (Number of tracks)/mm2.
//
// Surface is defined at the -Z surface.
// Direction                  -Z   +Z
