  // (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)
