- added code and config files for anti-e MVA training
- added trained anti-e MVA6 BDTs
- added code + python config to produce anti-e MVA6 tau ID discriminators
- tightened tau decay mode reconstruction parameters
  in order to reduce increase in jet -> tau fake-rate reported by Lucia and Simon
- added Pt thresholds for new high Pt tau reconstruction feature that neutral PFCandidates get
  merged with nearby tracks: now only tracks of Pt > 100 are considered as "seeds" for this merging feaure.
  This reduces the increase in jet -> tau fake-rate due to the fact that jets migrate from the tauPt < 20 GeV
  into the tauPt > 20 GeV region
