modularize analysis sequence

[cbernet]

We could think of modularizing more: e.g.

• TauAnalyzer
  • evaluate tau ID but do not select
  • possibly tau E correction
• Selector (for taus)
  • generic selector module (based on function object provided in cfg)
• MuAnalyzer
• ElectronAnalyzer
• Selector (signal muons)
• Selector (di-muon veto)
• Selector (third-lepton veto)
• DiLeptonAnalyzer
• DiMuonVeto (flags event or creates a collection with the selected muon pair)
• ThirdLeptonVeto (flags event or creates a collection with extra leptons)
• Selector (for di-leptons)
• JetAnalyzer
  • jet energy corrections
• Selector (for jets)
• Selector (select b jets)
• BJetSFAnalyzer
  • promote / demote
• TreeProducer
  • one TreeProducer class per channel, no common base class, make use of functions in a common module (e.g. book_tau, book_e)
