prepareEventVariablesFriendTree.py configuration required for the first stage of preparation of the friend trees including MVA training with 6/8/9 variables.
bsub_all.sh now has two configurations: first used for the production of the initial FTs, and the second used for the production of the FTs after the 6/8/9 variables MVA training.
Initial prepareEventVariablesFriendTree_NVAR.py configuration, as well ad the relevant readers finalMVA_2lss_NVAR.py imported into the user's workspace.
Some corrections made on the initial trainMVA_2lss.cxx.
