// (Description)
//   This is a primitive scorer class for scoring Surface Flux.
//  This Flux version assumes only for G4Tubs shape, and the surface
//  is defined at the Rmin 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                  Rmin Rmax
