- *
- * Revision 1.21 2004/05/21 21:42:12 gorelenk
- * Added PCH ncbi_pch.hpp
- *
- * Revision 1.20 2004/02/19 17:17:23 vasilche
- * Removed unused include.
- *
- * Revision 1.19 2003/07/17 20:07:56 vasilche
- * Reduced memory usage by feature indexes.
- * SNP data is loaded separately through PUBSEQ_OS.
- * String compression for SNP data.
- *
- * Revision 1.18 2003/06/02 16:06:38 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 1.17 2003/04/24 16:12:38 vasilche
- * Object manager internal structures are splitted more straightforward.
- * Removed excessive header dependencies.
- *
- * Revision 1.16 2003/03/14 19:10:41 grichenk
- * + SAnnotSelector::EIdResolving; fixed operator=() for several classes
- *
- * Revision 1.15 2003/03/11 15:51:06 kuznets
- * iterate -> ITERATE
- *
- * Revision 1.14 2003/02/24 18:57:22 vasilche
- * Make feature gathering in one linear pass using CSeqMap iterator.
- * Do not use feture index by sub locations.
- * Sort features at the end of gathering in one vector.
- * Extracted some internal structures and classes in separate header.
- * Delay creation of mapped features.
- *
- * Revision 1.13 2003/02/05 17:59:17 dicuccio

- *
- * Revision 1.11 2003/01/22 20:11:54 vasilche
- * Merged functionality of CSeqMapResolved_CI to CSeqMap_CI.
- * CSeqMap_CI now supports resolution and iteration over sequence range.
- * Added several caches to CScope.
- * Optimized CSeqVector().
- * Added serveral variants of CBioseqHandle::GetSeqVector().
- * Tried to optimize annotations iterator (not much success).
- * Rewritten CHandleRange and CHandleRangeMap classes to avoid sorting of list.
- *
- * Revision 1.10 2002/12/19 20:18:01 grichenk
- * Fixed test case for minus strand location
- *
- * Revision 1.9 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 1.8 2002/06/12 14:40:47 grichenk
- * Made some methods inline
- *
- * Revision 1.7 2002/05/24 14:58:55 grichenk
- * Fixed Empty() for unsigned intervals

- * best seq-id match in data sources and scopes. Updated tests.
- *
- * Revision 1.3 2002/02/15 20:35:38 gouriano
- * changed implementation of HandleRangeMap
- *
- * Revision 1.2 2002/01/23 21:59:31 grichenk
