Detailed Description

Description: Navigation school for the muon system This class defines which DetLayers are reacheable from each Muon DetLayer (DT, CSC and RPC). The reacheableness is based on an eta range criteria.

Author: : Stefano Lacaprara - INFN Padova stefa.nosp@m.no.l.nosp@m.acapr.nosp@m.ara@.nosp@m.pd.in.nosp@m.fn.i.nosp@m.t

Modification:

Chang Liu: The class links maps for nextLayers and compatibleLayers in the same time.
