* Revision 1000.1  2004/06/01 19:43:58  gouriano
* PRODUCTION: UPGRADED [GCC34_MSVC7] Dev-tree R1.23
*
* Revision 1.23  2004/05/17 21:03:14  gorelenk
* Added include of PCH ncbi_pch.hpp
*
* Revision 1.22  2003/10/21 13:48:51  grichenk
* Redesigned type aliases in serialization library.
* Fixed the code (removed CRef-s, added explicit
* initializers etc.)
*
* Revision 1.21  2003/04/29 18:31:09  gouriano
* object data member initialization verification
*
* Revision 1.20  2003/03/10 18:55:19  gouriano
* use new structured exceptions (based on CException)
*
* Revision 1.19  2000/11/07 17:26:26  vasilche
* Added module names to CTypeInfo and CEnumeratedTypeValues
* Added possibility to set include directory for whole module
*
* Revision 1.18  2000/08/25 15:59:25  vasilche
* Renamed directory tool -> datatool.
*
* Revision 1.17  2000/07/11 20:36:30  vasilche
* Removed unnecessary generation of namespace references for enum members.
* Removed obsolete methods.
*
* Revision 1.16  2000/06/16 16:31:41  vasilche
* Changed implementation of choices and classes info to allow use of the same classes in generated and user written classes.
*
* Revision 1.15  2000/04/17 19:11:09  vasilche
* Fixed failed assertion.
* Removed redundant namespace specifications.
*
* Revision 1.14  2000/04/12 15:36:53  vasilche
* Added -on <namespace> argument to datatool.
* Removed unnecessary namespace specifications in generated files.
*
* Revision 1.13  2000/04/07 19:26:36  vasilche
* Added namespace support to datatool.
* By default with argument -oR datatool will generate objects in namespace
* NCBI_NS_NCBI::objects (aka ncbi::objects).
* Datatool's classes also moved to NCBI namespace.
*
* Revision 1.12  2000/03/07 20:05:00  vasilche
* Added NewInstance method to generated classes.
*
* Revision 1.11  2000/03/07 14:06:34  vasilche
* Added generation of reference counted objects.
*
* Revision 1.10  2000/02/02 14:57:07  vasilche
* Added missing NCBI_NS_NSBI and NSBI_NS_STD macros to generated code.
*
* Revision 1.9  2000/02/01 21:48:09  vasilche
* Added CGeneratedChoiceTypeInfo for generated choice classes.
* Removed CMemberInfo subclasses.
* Added support for DEFAULT/OPTIONAL members.
* Changed class generation.
* Moved datatool headers to include/internal/serial/tool.
*
* Revision 1.8  2000/01/10 19:46:47  vasilche
* Fixed encoding/decoding of REAL type.
* Fixed encoding/decoding of StringStore.
* Fixed encoding/decoding of NULL type.
* Fixed error reporting.
* Reduced object map (only classes).
*
* Revision 1.7  1999/12/28 18:56:00  vasilche
* Reduced size of compiled object files:
* 1. avoid inline or implicit virtual methods (especially destructors).
* 2. avoid std::string's methods usage in inline methods.
* 3. avoid string literals ("xxx") in inline methods.
*
* Revision 1.6  1999/12/17 19:05:19  vasilche
* Simplified generation of GetTypeInfo methods.
*
* Revision 1.5  1999/12/01 17:36:28  vasilche
* Fixed CHOICE processing.
*
* Revision 1.4  1999/11/18 17:13:07  vasilche
* Fixed generation of ENUMERATED CHOICE and VisibleString.
* Added generation of initializers to zero for primitive types and pointers.
*
* Revision 1.3  1999/11/16 15:41:17  vasilche
* Added plain pointer choice.
* By default we use C pointer instead of auto_ptr.
* Start adding initializers.
*
* Revision 1.2  1999/11/15 19:36:20  vasilche
* Fixed warnings on GCC
