Updates for the pre-approval
Electron QCD is now normalised to MC; new unfolding files
Fixed a bug with scale-up unfolding file
Different line styles (greyscale-friendly)
Fixed total error in fit tables: errors summed linearly rather than in quadrature
Added an option for a ratio plot in mc comparison
Added a feature of changing normalisation of the histograms, including errors
Many updates to control plots
Updated the binning of ST/HT/MET log plots
