 ***************************************************************************
 * Description: Overrides (mostly for the swap functions, 
 *              print functions of each bank)
 *      
 *
 *   change log
 *
 ***************************************************************************
 * $Log: TPCV1P0.Banks.cxx,v $
 * Revision 1.3  2007/12/24 06:04:31  fine
 * introduce OLDEVP namespace to allow ole and new EVP library concurrently
 *
 * Revision 1.2  1999/07/02 04:43:22  levine
 * Many changes -
 *  navigates to head of TPCP bank independent of position.
 *  move declarations out of loops where they were upsetting some compilers
 *  suppress output from class libraries with run-time switch EventReader.verbose
 *  added TPCV2P0_CPP_SR::getAsicParams()
 *
