0006     \brief Selects good muons
0007
0008     The muon selector returns a flag (see pat::ParticleStatus) based on one of the possible
0009     selections: reconstruction-based (global muons) or muId based (various algorithms),
0010     or custom (user-defined set of cuts). This is driven by the configuration parameters
0011     (see the PATMuonCleaner documentation for configuration details).
0012
0013     The parameters are passed to the selector through an MuonSelection struct.
0014     (An adapter exists for use in CMSSW: reco::modules::ParameterAdapter< pat::MuonSelector >.)
