 * Revision 1.1  2007/08/06 20:50:48  shorne
 * First commit of h323plus
 *
 * Revision 1.6  2005/11/30 13:05:01  csoutheren
 * Changed tags for Doxygen
 *
 * Revision 1.5  2004/04/18 04:38:16  rjongbloed
 * Changed all operators that return BOOL to return standard type bool. This is primarily
 *   for improved compatibility with std STL usage removing many warnings.
 *
 * Revision 1.4  2002/09/16 01:14:15  robertj
 * Added #define so can select if #pragma interface/implementation is used on
 *   platform basis (eg MacOS) rather than compiler, thanks Robert Monaghan.
 *
 * Revision 1.3  2002/08/05 10:03:47  robertj
 * Cosmetic changes to normalise the usage of pragma interface/implementation.
 *
 * Revision 1.2  2001/03/19 05:51:35  robertj
 * Added ! operator to do !IsNULL(), so cannot use it accidentally.
 *
 * Revision 1.1  2001/03/02 06:59:57  robertj
 * Enhanced the globally unique identifier class.
