 Description: reco::Muon producer that can fill various information:
              - track-segment matching
              - energy deposition
              - muon isolation
              - muon hypothesis compatibility (calorimeter)
              Acceptable inputs:
              - reco::TrackCollection
              - reco::MuonCollection
              - reco::MuonTrackLinksCollection
