Importing CMG-TTH analyzers and adding a working example

I imported some stuff from CMG TTHAnalysis SUSY (basically one analyzer per object type) and all the c++ code in CMGTools/RootTools (if something should be removed, just let me know)
there is a working example under test/
There are few broken things with Electrons (MVA and Calibration) but I guess is no big deal for now.
