* PRODUCTION: UPGRADED [ORIGINAL] Dev-tree R1.5
*
* Revision 1.5  2003/12/01 19:04:22  grichenk
* Moved Add and Sub from serialutil to ncbimisc, made them methods
* of CRawPointer class.
*
* Revision 1.4  2003/04/15 16:18:55  siyan
* Added doxygen support
*
* Revision 1.3  2002/12/23 18:38:51  dicuccio
* Added WIn32 export specifier: NCBI_XSERIAL_EXPORT.
* Moved all CVS logs to the end.
*
* Revision 1.2  2000/10/13 20:22:46  vasilche
* Fixed warnings on 64 bit compilers.
* Fixed missing typename in templates.
*
* Revision 1.1  2000/09/18 20:00:10  vasilche
* Separated CVariantInfo and CMemberInfo.
* Implemented copy hooks.
* All hooks now are stored in CTypeInfo/CMemberInfo/CVariantInfo.
* Most type specific functions now are implemented via function pointers instead of virtual functions.
