// (Description)
//   This is a primitive scorer class for scoring only energy deposit.

//
// 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 dose deposit (x)
//              vs. weight (y) (Makoto Asai)
