* Revision 1000.1  2004/06/01 19:23:53  gouriano
* PRODUCTION: UPGRADED [GCC34_MSVC7] Dev-tree R1.13
*
* Revision 1.13  2004/05/21 21:42:13  gorelenk
* Added PCH ncbi_pch.hpp
*
* Revision 1.12  2004/03/16 15:47:28  vasilche
* Added CBioseq_set_Handle and set of EditHandles
*
* Revision 1.11  2004/02/09 19:18:54  grichenk
* Renamed CDesc_CI to CSeq_descr_CI. Redesigned CSeq_descr_CI
* and CSeqdesc_CI to avoid using data directly.
*
* Revision 1.10  2003/06/02 16:06:37  dicuccio
* Rearranged src/objects/ subtree.  This includes the following shifts:
*     - src/objects/asn2asn --> arc/app/asn2asn
*     - src/objects/testmedline --> src/objects/ncbimime/test
*     - src/objects/objmgr --> src/objmgr
*     - src/objects/util --> src/objmgr/util
*     - src/objects/alnmgr --> src/objtools/alnmgr
*     - src/objects/flat --> src/objtools/flat
*     - src/objects/validator --> src/objtools/validator
*     - src/objects/cddalignview --> src/objtools/cddalignview
* In addition, libseq now includes six of the objects/seq... libs, and libmmdb
* replaces the three libmmdb? libs.
*
* Revision 1.9  2003/04/24 16:12:38  vasilche
* Object manager internal structures are splitted more straightforward.
* Removed excessive header dependencies.
*
* Revision 1.8  2003/03/14 19:10:41  grichenk
* + SAnnotSelector::EIdResolving; fixed operator=() for several classes
*
* Revision 1.7  2003/03/13 13:02:36  dicuccio
* Added #include for annot_object.hpp - fixes obtuse error for Win32 builds
*
* Revision 1.6  2002/07/08 20:51:01  grichenk
* Moved log to the end of file
* Replaced static mutex (in CScope, CDataSource) with the mutex
* pool. Redesigned CDataSource data locking.
*
* Revision 1.5  2002/05/06 03:28:47  vakatov
* OM/OM1 renaming
*
* Revision 1.4  2002/02/21 19:27:05  grichenk
* Rearranged includes. Added scope history. Added searching for the
* best seq-id match in data sources and scopes. Updated tests.
*
* Revision 1.3  2002/01/23 21:59:31  grichenk
* Redesigned seq-id handles and mapper
*
* Revision 1.2  2002/01/16 16:25:57  gouriano
* restructured objmgr
*
* Revision 1.1  2002/01/11 19:06:18  gouriano
* restructured objmgr
