40// (Description)
41// This is a primitive scorer class for scoring only Surface Flux.
42// Flux version assumes only for G4Sphere shape.
43//
44// Surface is defined at the inside of sphere.
45// Direction -Rmin +Rmax
46// 0 IN || OUT ->|<- |
47// 1 IN ->| |
48// 2 OUT |<- |
49//
50// Created: 2005-11-14 Tsukasa ASO, Akinori Kimura.
51// 29-Mar-2007 T.Aso, Bug fix for momentum direction at outgoing flux.
52// 2010-07-22 Introduce Unit specification.
53// 2010-07-22 Add weighted and divideByAre options
