* $Log: parser.hpp,v $
* Revision 1000.1  2004/04/12 17:16:16  gouriano
* PRODUCTION: UPGRADED [CATCHUP_003] Dev-tree R1.10
*
* Revision 1.10  2004/02/26 16:23:48  gouriano
* Skip datatype constraints when parsing ASN.1 spec
*
* Revision 1.9  2004/02/25 19:45:48  gouriano
* Made it possible to define DEFAULT for data members of type REAL
*
* Revision 1.8  2000/12/15 15:38:35  vasilche
* Added support of Int8 and long double.
* Added support of BigInt ASN.1 extension - mapped to Int8.
* Enum values now have type Int4 instead of long.
*
* Revision 1.7  2000/11/15 20:34:43  vasilche
* Added user comments to ENUMERATED types.
* Added storing of user comments to ASN.1 module definition.
*
* Revision 1.6  2000/11/14 21:41:14  vasilche
* Added preserving of ASN.1 definition comments.
*
* Revision 1.5  2000/11/01 20:36:11  vasilche
* OPTIONAL and DEFAULT are not permitted in CHOICE.
* Fixed code generation for DEFAULT.
*
* Revision 1.4  2000/09/26 17:38:17  vasilche
* Fixed incomplete choiceptr implementation.
* Removed temporary comments.
*
* Revision 1.3  2000/08/25 15:58:47  vasilche
* Renamed directory tool -> datatool.
*
* Revision 1.2  2000/04/07 19:26:11  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 1.1  2000/02/01 21:46:21  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 1.11  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 1.10  1999/11/19 15:48:11  vasilche
* Modified AutoPtr template to allow its use in STL containers (map, vector etc.)
*
* Revision 1.9  1999/11/15 19:36:18  vasilche
* Fixed warnings on GCC
