// (Description)
//   This is a primitive scorer class for scoring only track length.
//   The tracks which passed a geometry is taken into account.
// 
//
// Created: 2005-11-14  Tsukasa ASO, Akinori Kimura.
// 2010-07-22   Introduce Unit specification.
// 2020-10-06   Use G4VPrimitivePlotter and fill 1-D histo of track length 
//              vs. number of tracks (not weighted)             (Makoto Asai)
