/* History of cvs commits:
 *
 * $Log$
 * Revision 1.69  2006/11/14 17:11:15  hristov
 * Removing inheritances from TAttLine, TAttMarker and AliRndm in AliModule. The copy constructor and assignment operators are moved to the private part of the class and not implemented. The corresponding changes are propagated to the detectors
 *
 * Revision 1.68  2006/08/11 12:36:25  cvetan
 * Update of the PHOS code needed in order to read and reconstruct the beam test raw data (i.e. without an existing galice.root)
 *
 * Revision 1.67  2006/04/07 08:42:00  hristov
 * Follow AliAlignObj framework and remove AliPHOSAlignData (Yu.Kharlov)
 *
 * Revision 1.66  2006/03/24 21:39:33  schutz
 * Modification needed to include PHOS in the global trigger framework
 *
 * Revision 1.65  2006/03/07 18:56:25  kharlov
 * CDB is passed via environment variable
 *
 * Revision 1.64  2005/11/03 13:09:19  hristov
 * Removing meaningless const declarations (linuxicc)
 *
 * Revision 1.63  2005/07/26 13:32:39  kharlov
 * Restoring raw data fit from version of 29-Aug-2004
 *
 * Revision 1.62  2005/07/06 10:10:32  hristov
 * Moving the functions used to initialize TF1 and TF2 to the pivate part of the class
 *
 * Revision 1.61  2005/05/28 12:10:07  schutz
 * Copy constructor is corrected (by T.P.)
