// (Description)
//   This is a primitive scorer class for scoring Surface Flux.
//  Current version assumes only for G4Box shape, and the surface
//  is defined at the -Z plane of the box.
//   The surface flux is given in the unit of area. 
//    e.g.  sum of 1/cos(T)/mm2,  where T is a incident angle of the
//                                track on the surface.
//
//
// Surface is defined at the -Z surface.
// Direction                  -Z   +Z
