+Revision 1.6  2000/10/18 11:42:06  morsch
+- AliMUONRawCluster contains z-position.
+- Some clean-up of useless print statements during initialisations.
+
+Revision 1.5  2000/10/04 18:50:05  morsch
+In Init(): (*fDpxD)[fNsec-1]=fDpx;
+
+Revision 1.4  2000/10/03 21:48:07  morsch
+Adopt to const declaration of some of the methods in AliSegmentation.
+
+Revision 1.3  2000/06/29 12:34:09  morsch
+AliMUONSegmentation class has been made independent of AliMUONChamber. This makes
+it usable with any other geometry class. The link to the object to which it belongs is
+established via an index. This assumes that there exists a global geometry manager
+from which the pointer to the parent object can be obtained (in our case gAlice).
