////////////////////////////////////////////////////////////////////////////////
// (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.
//
// Created: 2005-11-14  Tsukasa ASO, Akinori Kimura.
// 2010-07-22   Introduce Unit specification.
// 2010-07-22   Add weighted option
