// (Description)
//   This is a primitive scorer class for scoring minimum energy of
//  newly produced particles in the geometry.
//
// Created: 2005-11-17  Tsukasa ASO, Akinori Kimura.
// 2010-07-22   Introduce Unit specification.
// 2020-10-06   Use G4VPrimitivePlotter and fill 1-D histo of kinetic energy (x)
//              vs. track weight (y)                 (Makoto Asai)
