// (Description)
//   This is a primitive scorer class for scoring number of tracks,
//   where only tracks passing through the geometry are taken 
//  into account.
//
// 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. current * track weight (y)               (Makoto Asai)
