HltEfficiencyChecker should switch to using functors+FunTuple rather than TupleTools+MCDecayTreeTuple
What is the future of tupling in MooreAnalysis? I see development of TupleTools for MooreAnalysis Analysis!604 (merged) while on the other hand we want to remove all TupleTools https://gitlab.cern.ch/lhcb-dpa/project/-/issues/7.
To satisfy https://gitlab.cern.ch/lhcb-dpa/project/-/issues/7, all remaining TupleTools were moved to MooreAnalysis
in !55 (merged).
Tupling should be done with FunTuple+functors rather than the outdated MCDecayTreeTuple+TupleTools. Please see discussion below for progress/bottlenecks on this.
