adding macros for prefit postfit variables

I added all macros I used to preduce prefit post fit plots. Maybe they are not the most efficient, but they work.

Inputs for these plots are here: /nfs/at3/scratch2/mcasolino/VLQInputsForFit/

olep: 0lep_22_08_morevariables

1lep: 1lep_23_08_morevariables

For 1 lep as we discussed c1l3b should be produced.

I suggest you slim as well inputs so when the combi fit will be applied you don't need to open huge inputs.
