Converts a McEventCollection into an TruthParticleContainer (ie: converts it into an AOD compliant collection).

@in mcEvts the McEventCollection holding the HepMC::GenEvent we want to convert into a TruthParticleContainer @in genEvtIndex the index to the HepMC::GenEvent to be converted @out mcParts a valid pointer to a TruthParticleContainer which will be filled with adaptors to HepMC::GenParticles.

Create a map to enhance access between GenParticles and TruthParticles
