Class describing a truth vertex in the MC record
The xAOD truth record mimicks the structure of HepMC. Truth particles and truth vertices form a decay tree. Where each truth particle is connected to a single production and decay vertex. And each vertex is connected to one or more incoming, and one or more outgoing particles.
