Statistical uncertainty shapes

“addStatShapes.py” adds statistical shape errors into data card and
corresponding histograms into “plots.root” file.
“addStatShapesAllDataCards.py” recreates the individual data cards for
each signal.
Note that before adding the stat shapes to data cards, the individual
data cards has to be created using “makeAllDataCards.py”. Then, run the
“addStatShapes.py” to get the stat shapes in the signal separation data
card (with both signals). Finally, run “addStatShapesAllDataCards.py”
to modify the individual signal data cards for stat shapes.
In each script, there are input parameters (input files, output files
and thresholds) that need to be modified accordingly before running.
