+Revision 1.17.1  2006/12/15
+         Added methods:
+            DetToSectorRF(...) to get pad corners
+          coordinates in its sector reference frame;
+            GetVolumePath(Int_t sector, Char_t *path)
+          to get the volume path for a sector
+            GetVolumePath(Int_t sector, Int_t plate, Int_t strip, Char_t *path)
+          to get the volume path for a strip
+         (A.De Caro, M.Di Stefano)
+Revision 1.7  2006/07/12 16:03:59  arcelli
+updates to match the new numbering of the TOF/TRD mother volumes in FRAME (ALICE convention)
