Persist relations for non-reconstructed MC/Particles
Currently, only relations are stored for MCParticles which have been reconstructed. (In the specific cases where the event type describes a specific signal decay via EvtGen, those particles are also added) This prevents us from doing rudimentary efficiency studies on our MC samples via the MCTuple (MCDecayTreeTuple) functionality. To fix this, a relation table between protoparticles and MCParticles needs to be stored also for the MCParticles in /Event/MC/Particles
.
At the same time, one can question whether the duplication of MCParticles that is present at the moment, with the partial cloning to /Event/HLT2/MC/Particles
, is needed.
