0011  Description: MuonNumbering class to handle the conversion
0012  to MuonBaseNumber from the ExpandedNodes history
0013
0014  Implementation:
0015  in the xml muon constant section one has to define
0016  level, super and base constants (eg. 1000,100,1) and
0017  the start value of the copy numbers (0 or 1)
