For review it's better to look at the two commits separately. This will clarify a few things.

Rebased onto master and updated the code. Please review again @HerrHorizontal @RHofsaess

This producer should be ready to merege. Debug output looks like this:

Please review again @HerrHorizontal @RHofsaess . The twiki states The SFs should be applied for any AK4 CHS jet in MC that passes the [PileUpJetID](https://twiki.cern.ch/twiki/bin/edit/CMS/PileUpJetID?topicparent=CMS.PileupJetIDUL;nowysiwyg=1) and is also geometrically matched (ΔR < 0.4) to AK4 Gen jets. So I updated the producer to do exactly this. https://twiki.cern.ch/twiki/bin/view/CMS/PileupJetIDUL#Data_MC_Efficiency_Scale_Factors

Note that the 'producer:ValidZllGenJetsProducer' followed by the producer:RecoJetGenJetMatchingProducer need to run first.
