Detailed Description

Base class for GlobalMuonTrajectoryBuilder and L3MuonTrajectoryBuilder Provide common tools and interface to reconstruct muons starting from a muon track reconstructed in the standalone muon system (with DT, CSC and RPC information). It tries to reconstruct the corresponding track in the tracker and performs matching between the reconstructed tracks in the muon system and the tracker.
