//
//  HParticleSrc - Data container for Geant tracks at particle level
//
//  The purpose of HParticleSrc is to store particle parameters before
//  they have been digitized. See the documentation (link below).
//
//  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:
//
//      HParticleSrc *part1 = new HParticleSrc(50.,50.,50.,938.);
//
//      HParticleSrc *part2 = new HParticleSrc(30.,30.,30.,938.);
//
//      Float_t pxSum = part1.Px() + part2.Px()
//      .....
//
//  HParticleSrc's can be initialized as follows:
//      part = new HParticleSrc();
//      part = new HParticleSrc(Double_t px, Double_t py, Double_t pz);
//      part = new HParticleSrc(Double_t px, Double_t py, Double_t pz, Double_t m);
//      part = new HParticleSrc(Int_t Pid, Double_t px, Double_t py, Double_t pz);
//      part = new HParticleSrc(Int_t trackNumber, Int_t Pid, Double_t px, Double_t py, Double_t pz);
//
