36 // (Description)
37 // This is a primitive scorer class for scoring only track length.
38 // The tracks which passed a geometry is taken into account.
39 //
40 //
41 // Created: 2005-11-14 Tsukasa ASO, Akinori Kimura.
42 // 2010-07-22 Introduce Unit specification.
43 // 2020-10-06 Use G4VPrimitivePlotter and fill 1-D histo of track length
44 // vs. number of tracks (not weighted) (Makoto Asai)
