// (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.
//
//
// Created: 2005-11-14  Tsukasa ASO, Akinori Kimura.
// 2010-07-22   Introduce Unit specification.
// 2010-07-22   Add weighted option
// 2020-10-06   Use G4VPrimitivePlotter and fill 1-D histo of kinetic energy (x)
//              vs. cell flux * track weight (y)         (Makoto Asai)
