// (Description)
//   This is a primitive scorer class for scoring cell flux.
//   The Cell Flux is defined by  a track length divided by a geometry
//   volume, where only tracks passing through the geometry are taken
//  into account. e.g. the unit of Cell Flux is mm/mm3.
//
//   If you want to score all tracks in the geometry volume,
//  please use G4PSCellFlux.
