//
//  HParticleSim - Data container for simulated identified particles
//
//  Currently, HParticleSim is simply an HParticle. Geant track number is
//  not propagated due to possibility of multiple Geant tracks contributing
//  to one particle. Indices to hits/tracks must be used to access Geant info.
//
//  This class derives from HParticle, which in turn derives from
//  TLorentzVector, so that all of the functions available to
//  TLorentzVector can be performed on HParticle objects:
//
//      HParticleSim *part1 = new HParticleSim(50.,50.,50.,938.);
//
//      HParticleSim *part2 = new HParticleSim(30.,30.,30.,938.);
//
//      Float_t pxSum = part1.Px() + part2.Px()
//      .....
