40// (Description)
41// This is a primitive scorer class for scoring Surface Flux.
42// Current version assumes only for G4Tubs shape, and the surface
43// is fixed on inner plane of the tube.
44//
45// Surface is defined at the innner surface of the tube.
46// Direction R R+dR
47// 0 IN || OUT ->|<- |
48// 1 IN ->| |
49// 2 OUT |<- |
50//
51// Created: 2007-03-29 Tsukasa ASO
52// 2010-07-22 Introduce Unit specification.
53// 2010-07-22 Add weighted and divideByArea options
