 * Revision 1.3  2001/12/10 15:25:11  mpowers
 * Now properly extending EOKeyValueCoding.
 *
 * Revision 1.2  2001/04/28 14:12:23  mpowers
 * Refactored cloning/copying into KeyValueCodingUtilities.
 *
 * Revision 1.1  2001/03/29 03:29:49  mpowers
 * Now using KeyValueCoding and Support instead of Introspector.
 *
 * Revision 1.2  2001/03/28 16:12:30  mpowers
