40// (Description)
41// This is a primitive scorer class for scoring Surface Flux.
42// Current version assumes only for G4Box shape, and the surface
43// is fixed on -Z plane.
44//
45// Surface is defined at the -Z surface.
46// Direction -Z +Z
47// 0 IN || OUT ->|<- |
48// 1 IN ->| |
49// 2 OUT |<- |
50//
51// Created: 2005-11-14 Tsukasa ASO, Akinori Kimura.
52//
53// 18-Nov-2005 T.Aso, To use always positive value for anglefactor.
54// 29-Mar-2007 T.Aso, Bug fix for momentum direction at outgoing flux.
55// 2010-07-22 Introduce Unit specification.
56// 2010-07-22 Add weighted and divideByAre options
