merge mvaMET code for miniAOD in 72X
adding maunaully the missing files, corresponding commits was lost in limbs
add example config file
update config files, separate lepton info computation
Merged 72X-mvaMETForMiniAOD from repository cms-met

Take pileup jet ID algo from MVAMET update.

Conflicts:
	RecoJets/JetProducers/src/PileupJetIdAlgo.cc
HeppyCore: local multithread fixes:
- get exception stack traces when running multithread,
- support non-pickleable configuration with multithread
  (needed for the AutoFillTreeProducer in Heppy)
HeppyCore: provide also information on the component in which the exception was thrown
Multiprocessing fixes from Heppy
Heppy: use tfileservice in NumpyTreeProducer when available
add missing parameter in default config
Heppy: add xsection
Heppy LeptonAnalyzer: updates and more sensible defaults:
- include EAs for isolation in Phys14 25ns samples
  (Data2012 ones are also provided)
- fix electron isolations for R=0.4: before deltaBeta was dummy,
  and rho*EA was using the R=0.3 effective area
- the deltaR cut in the electron-muon cleaning was applied to
  deltaR2 instead of to deltaR, now fixed.
- the default electron tight id was 'MVA' but MVA Id is not yet
  in Heppy so it was dummy: switched to Cuts_2012
- Cuts_2012 electron tightId moved to full5x5 clusters
Heppy: add timing
