ElectronPhotonSelectorTools: Add option to use avg mu in el LH tool
Normally one has to pass the avg mu to the accept function.
The goal of this merge is to get mu automatically from EventInfo
so one can call the tool via the nominal accept(IParticle*)
function.
Does not affect existing functionality, only adds new option useAverageMu
.
Intended mainly for analysis of online electrons, where one needs to use mu
but wants to use the tool via AsgSelectionAlg
.
