// (Description)
//   This is a primitive scorer class for scoring Surface Flux.
//  Flux version assumes only for G4Sphere shape, and the surface
//  is defined at the inside of the sphere.
//   The current is given in the unit of area. 
//    e.g.  (Number of tracks)/mm2.
//
// Surface is defined  at the inside of sphere.
// Direction                  -Rmin   +Rmax
