Early parton level veto (before beam remnants and resonance showers)
1) Sort the original incoming process. After this step is performed, the following assignments have been made: eventProcessOrig - the original incoming process eventProcess - the final-state of the incoming process with resonance decays removed (and resonances themselves now with positive status code) typeIdx[0/1/2] - Indices into 'eventProcess' of light jets/heavy jets/other typeSet[0/1/2] - Indices into 'event' of light jets/heavy jets/other workEvent - partons from the hardest subsystem + ISR + FSR only
For the shower-kT scheme, do not perform any veto here, as any vetoing will already have taken place in doVetoStep.
Debug printout.

Work event (partons from hardest subsystem + ISR + FSR)
2) Light/heavy jets: iType = 0 (light jets), 1 (heavy jets)
2a) Find particles which will be passed from the jet algorithm. Input from 'workEvent' and output in 'workEventJet'.

2b) Run jet algorithm on 'workEventJet'. Output is stored in jetMomenta.
2c) Match partons to jets and decide if veto is necessary

Switch for merging in the shower-kT scheme. Needed here because the scheme uses different UserHooks functionality.

Event records to store original incoming process, final-state of the incoming process and what will be passed to the jet algorithm. Not completely necessary to store all steps, but makes tracking the steps of the algorithm a lot easier.

Constants to be changed for debug printout or extra checks.
Main implementation of JetMatching class. This may be split out to a separate C++ file if desired, but currently included here for ease of use.
