0005  *
0006  *  Model of a Muon Drift Tube chamber.
0007  *   
0008  *  A chamber is a GeomDet; the associated reconstructed objects are 
0009  *  4D segments built in the chamber local reference frame.
0010  *  The chamber is composed by 2 or three DTSuperLayer, which in turn are 
0011  *  composed by four DTLayer each.
