working on eleMva calculation
Old eleMva resurrected, working on protections / bitmasks
add back old dataformat
get old electron mva output in PFEG mostly inline with PFElectronAlgo
fill electron veto bits
change to new model for extra information, now stores ElementsInBlock for gsfecal cluster and tracks that are not conversions
fix crash in PFEGammaAlgo when no brems present
include function to switch on PFEG and off gsfElectrons,etc
fix crash in BremTangents
working on PFEGCandidate checker
some simply analyzers and batch scripts
protections part 1

Conflicts:
	RecoParticleFlow/PFProducer/plugins/PFProducer.cc
protections part 2
protections part 3
fix bad merge conflict resolution
Protections against spurious PFclusters using residual minimization
customization to turn on EGammaGED
customize script for PFEG + GED switch, and associated patches for some validation analyzers
fixes to make the matrix really run (remove a few things in harvesting for oldpfphotons)
add even more cluster protections
