Reorganize and add b-tagging SF studies
Sorry, this is a big PR...
- Reorganize the plotter modules to share as much as possible the object definitions in
definitions.py
andgenDefinitions.py
- Put the utility functions for the modules in
utils.py
- Add plotter module and script to study effect of b-tagging scale factor application
- Add utilities to read histograms to reweight events, and to apply fixed-working point b tagging scale factors (for now only a single working point)
- Rework binning optimization code
- Gen vs. reco plots: a single GEN selection with 1 lepton is now defined, and the reco channels (e/mu) fork out from there.
- Update README
