Remove useless path.
Setup HT as SumHT plot from Handle<recoExoticaValidationHT> product.sumEt().
Book SumEt histogram in case recObject contains MET, for 'recMatches' case.
Remove useless plots: genAnyMET, AnyMETMaxPt2. Implement a map<int, double> = map<pdgId, SumEt> to record the SumEt for each type of recLabels, especially each type of MET (other kinds of objects get SumEt set to -1). Fix histogram booking and filling.
