on #10751\r\nDue to comments in #10750\r\n\r\nAdd jetFlavourInfo to ak4 and ak8 jet collections, to be able to identify gluon splitting to bb.\r\nAdd lepton matching for identification of hadronic taus.\r\n\r\nWith this scheme:\r\nb,c can be identified by either j.hadronFlavour() (hadron definition) or j.partonFlavour() (algorithmic definition) or j.genParton().pdgId() (physics definition)\r\ng,u,d,s can be identified by j.genParton().pdgId() (physics definition)\r\ngluon splitting to bb can be identified roughly by (j.genParton().pdgId()==21 && len(j.jetFlavourInfo().getbHadrons())==2 )\r\n\r\nThe size increase (edmEventSize) for MiniAOD (on 1300 ttbar events) when adding JetFlavourInfo and lepton matching is the following:\r\nwithout JetFlavourInfo:\r\npatJets_slimmedJets__PAT. 32977.1 2663.08\r\npatJets_slimmedJetsAK8__PAT. 1141.85 251.157\r\nwith JetFlavourInfo:\r\npatJets_slimmedJets__PAT. 33015.2
