Detailed Description

Description: Filter to see if there are heavy flavor GenJets in this event

Implementation: The implementation is simple, it loops over the GenJets and checks if any constituents have a pdg ID that matches a list. It also has a switch to count objects from a gluon parent, so the user can turn off counting gluon splitting.
