 * FIxed include guards, doxygen groups
 *
 * Revision 1.2  2004/05/03 12:41:35  dicuccio

 * Revision 1.3  2004/04/15 12:57:43  lebedev
 * Changed GetObject to return NULL or const pointer based on given position
 *
 * Revision 1.2  2004/03/11 17:19:32  dicuccio
 * Use TSeqRange instead of TRange.  Use gui/gui instead of gui/types
