Adding Efficiency plots weighted by mcEventsWeights.at(0) in CutManager

I add such plots in combination with the GetXSectionTool, in order to make user-friendly and "fast" the calculation of the yield in easyjet.

The (Thomas') idea is basically to rescale these plots by the total weight :

weight = (mcEventWeight/SumOfWeight) x filterEfficiency x kFactor x crossSection * luminosity

which will be available through post-rocessing scripts that utilize the GetXSectionTool. Then we will be able to have cutflow plots in terms of yield.

Testing the implementation in bbyy so far.
