// (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
//   0  IN || OUT            ->|<-  |        fFlux_InOut
//   1  IN                   ->|    |        fFlux_In
//   2  OUT                    |<-  |        fFlux_Out

// Created: 2005-11-14  Tsukasa ASO, Akinori Kimura.

// 18-Nov-2005  T.Aso,  To use always positive value for anglefactor.
//                      Bug fix. Area definition.
