// (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
//   0  IN || OUT            ->|<-  |      fCurrent_InOut
//   1  IN                   ->|    |      fCurrent_In
//   2  OUT                    |<-  |      fCurrent_Out

// 17-Nov-2005 T.Aso, Bug fix for area definition.
// 31-Mar-2007 T.Aso, Add option for normalizing by the area.
// 2010-07-22   Introduce Unit specification.
