constructor requiring name, ID, and charge
Units ID: defined by PDG group (particles are +ve, antipart are -ve) also consistent with the Pythia definitions charge: fraction of proton charge mass cLifetime: c*time Default mass=0 and cLifetime is -1 which means stable (width= 0.) These defaults exist because many very basic MC generators may produce only massless stable particles in the event record.

constructor requiring name, ID, and charge
note, this constructor is redundant to the one above, i.e. one could use: new HepMC::ParticleData(string("electron"),11,-1,0.000511,-1,.5); but we keep it because it is convenient.

returns the particle id with the seventh digit removed for susy/excited/technicolor particles. Thus en excited electron (40000011) would be returned as 11 Useful only internally for sorting particles!
