regulariz update. plotter update.

[vberta]

In this pr is included:

• regularization update to the new FW. to produce the input for regularization you must use the (commented) binning added in analysisOnGen
• big update of prepareAngularCoeff and plotter_fitResult. to use them:

from analysisOnGen/ python scripts/prepareAngularCoeff.py -o genInputFileName -i GenInfoPath/Name.root

from Fit/ python plotter_fitResult.py -o outPutFileName -f /scratchnvme/emanca/wproperties-analysis/Fit/fit_Wplus_reco.root -u 1 -c 0 -s 0 -i ../analysisOnGen/genInputFileName.root --suffList reco

Other advanced usages are available. For instance, the plotter with c=1 and --suffList gen, reco can be used to compare reco and gen fit.
