Build the mu-mu-gamma filter sequence

Combine dimuons and photons to mumugamma candidates requiring

trailing muon pt + photon et > 20 GeV
distance between photon and near muon deltaR < 1.5
sum of invariant masses of the mmg and mm systems < 200 GeV
invariant mass of the mmg system > 40 GeV dimuon = daughter(0) leading muon = daughter(0).daughter(0) trailing muon = daughter(0).daughter(1) photon = daughter(1)
