// Description:
//  Class BgsGentleGenocide
//
//      A process that prevents the associated particle from being tracked
//      if it has traveled more than the specified number of steps and
//      falls below the specified kinetic energy.
//
//      To fix an apparent "loophole" in hadronic ionization for tritium
//
// Environment:
//  Software developed for the BaBar Detector at the SLAC B-Factory.
