Resolve "Dynamic/Automatic blinding in plotter"

Release notes

Added options blinding.SoverB and blinding.SoverSqrtSpB to plotting classes allowing for automatic blinding of data in signal sensitive bind (if the thresholds specified via these options are exceeded the data counts+errors in the respective bin are set to zero). The bin-by-bin values for s and b are determined from the sum of all histograms marked via ".isSignal" and ".isBackground" respectively in the process definition file used by the plotter (specified via "histogramProcesses" in the master config file). The blinding is then applied to all histograms/processes marked as ".isData"
