// (Description)
//   This is a primitive scorer class for scoring cell flux.
//   The Cell Flux is defined by  a sum of track length divided 
//   by the geometry volume, where all of the tracks in the geometry 
//   are taken into account. 
//
//   If you want to score only tracks passing through the geometry volume,
//  please use G4PSPassageCellFlux.
