Merge pull request #120 from cbotta/CMG_MiniAOD_Lite_V6_0_from-CMSSW_7_0_6

We might want to backport to 5.3.X the new IP variables.
Secondary vertices from IVF
MC matching for SVs (to be optimized)
Faster search for matched genparticle. now time seems to be mostly from the reading of the packedGen and packedPF
Insert SV analyzer in the multilepton cfg
Support for generator weights in skimAnalyzerCount and in
the tree producers from CMGTools/TTHAnalysis.
mcAnalysis will also pick up generator weights when present
text files to make plots of IVF quantities, and to train a per-SV MVA
include a few more samples
matching of IVFs
fix by-ref matching of secondary vertices
Add muon MVA ID input variables and a few extra ones
first macros to train MVA muon id
TTHAnalyisis: small updates to plotting tools
Heavy hadrons at gen-level
new tools for SV MVA
