* Added doxygen support
*
* Revision 1.7  2003/04/10 20:13:37  vakatov
* Rollback the "uninitialized member" verification -- it still needs to
* be worked upon...
*
* Revision 1.5  2003/03/26 16:13:32  vasilche
* Removed TAB symbols. Some formatting.
*
* Revision 1.4  2002/12/23 18:38:51  dicuccio
* Added WIn32 export specifier: NCBI_XSERIAL_EXPORT.
* Moved all CVS logs to the end.
*
* Revision 1.3  2000/10/13 20:22:45  vasilche
* Fixed warnings on 64 bit compilers.
* Fixed missing typename in templates.
*
* Revision 1.2  2000/10/03 17:22:32  vasilche
* Reduced header dependency.
* Reduced size of debug libraries on WorkShop by 3 times.
* Fixed tag allocation for parent classes.
* Fixed CObject allocation/deallocation in streams.
* Moved instantiation of several templates in separate source file.
*
* Revision 1.1  2000/09/18 20:00:01  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.
