TrigGlobalEfficiencyCorrectionTool support for 4mu4_L14MU3V trigger
Support for symmetric four-lepton triggers such as 4mu4_L14MU3V. Similarly to the trilepton case, the implementation allows exact calculation of the scale factor when the trigger is used alone (and with an arbitrary number of offline leptons), but not when used in combination with other triggers; for that, the toy-based calculation can be employed instead. If there's a use case for 4mu + single-muon trigger(s) combinations this could be added too, I think, but more complex combinations not easily...
