 * Hypertriton decaying into He3 + pion
 *
 * Author: Thomas Ullrich, May 99 (based on Geant4 code, see below) 
 ***************************************************************************
 *
 * The design of the StParticleDefinition class and all concrete
 * classes derived from it is largely based on the design of the 
 * G4ParticleDefinition class from Geant4 (RD44).
 * Although the code is in large parts different (modified or rewritten)
 * and adapted to the STAR framework the basic idea stays the same.

 * Revision 1.1  2010/01/28 20:01:00  jwebb
 * Added two 'STAR' particle classes.  The (fake) Dalitz particle, which
 * is really just a pi0 with its Dalitz decay branch at 100%.  It is added
 * so the embedding team can access it by the geant ID defined in gstar_part.g.
 * The hypertriton is also added.
 *
 * In both cases we define a fake PDG id in the header file StarPDGEncoding.hh.
