So no more memory moster message for binning analyser
Added in extra variable required to read muon reliso properly, need to change ntuple version to 10 for it to take effect though
updates to binning analyser including bug fix for ST
Add in ID, Iso and trigger efficiencies and a switch for if it is Iso selected

Updated test sample filename.
Updated electron MVA ID requirement to >0.5.
updated btag SFs to 2012, also made changes to event count analyser so that the btag weights and muon efficiencies are applied for the cutflow
