+Status flag implemented as UChar_t
+
+Revision 1.30 2007/10/04 13:08:52 arcelli
+updates to comply with AliTOFGeometryV5 becoming AliTOFGeometry
+
+Revision 1.29 2007/10/03 10:42:33 arcelli
+updates to handle new AliTOFcluster, inheriting form AliCluster3D
+
+Revision 1.28 2007/05/31 16:06:05 arcelli
+move instance of AliRawStream outside loop on DDL
+
+Revision 1.27 2007/05/02 16:31:49 arcelli
+Add methods to handle single event reconstruction. retrieval of Calib info moved to AliTOFReconstructor ctor, and passed via a pointer to AliTOFcalib
+
Revision 1.26 2007/04/30 19:02:24 arcelli
hopefully the last refinements for correct type conversion in calibration
