CPAlgorithms: updated experimental OverlapRemoval
New overlap removal scheme based on the nominal-OR decision, but run also for systematically-varied kinematic selections.
This is for experimental tests only at this stage, tagging @mdubovsk @ekourlit. I tested it locally on a small sample, and I see the intended behaviour in one electron event: the branch el_select_or
is set to 1, and at the same time we have el_select_loose_NOSYS
(the nominal ID+Iso+Pt+Eta cuts) set to 0, and all but one systematic variations also set to 0. Using the previous setup (run nominal-OR only, and only on the nominal kinematic selection), this electron event is not present at all.
