 * $Log: tabdump.cpp,v $
 * Revision 1.16  2006/11/20 20:05:58  dmorissette
 * First pass at improving generation of spatial index in .map file (bug 1585)
 * New methods for insertion and splittung in the spatial index are done.
 * Also implemented a method to dump the spatial index to .mif/.mid
 * Still need to implement splitting of TABMapObjectBlock to get optimal
 * results.
 *
 * Revision 1.15  2006/09/05 23:05:51  dmorissette
 * Added -spatialindex option to call TABMAPFile::DumpSpatialIndex() (bug 1585)
 *
 * Revision 1.14  2005/03/22 23:24:54  dmorissette
 * Added support for datum id in .MAP header (bug 910)
 *
 * Revision 1.13  2004/06/30 20:29:04  dmorissette
 * Fixed refs to old address [e-mail]
 *
 * Revision 1.12  2001/11/16 20:55:00  daniel
 * Added -d option: DumpMapFileBlockDetails()
 *
 * Revision 1.11  2001/09/19 14:33:19  warmerda
 * support mif files for dumping with -all
 *
 * Revision 1.10  2001/09/17 19:52:50  daniel
 * Added DumpViaSpatialIndex()
 *
 * Revision 1.9  2001/07/04 14:13:24  daniel
 * Added GetExtent() output in DumpCoordsys()
 *
 * Revision 1.8  2001/01/23 21:23:42  daniel
 * Added projection bounds lookup table, called from TABFile::SetProjInfo()
 *
 * Revision 1.7  2000/11/13 22:05:45  daniel
 * Added SearchIndex() - For string indexes only
 *
 * Revision 1.6  2000/10/18 03:57:55  daniel
 * Added DumpCoordsys()
 *
 * Revision 1.5  2000/02/28 17:14:31  daniel
 * Report indexed fields
 *
 * Revision 1.4  2000/01/15 22:30:45  daniel
 * Switch to MIT/X-Consortium OpenSource license
 *
 * Revision 1.3  1999/12/14 02:24:41  daniel
 * Use IMapInfoFile::SmartOpen()
 *
 * Revision 1.2  1999/09/20 14:27:49  warmerda
 * Use access of "rb" instead of "r".
 *
 * Revision 1.1  1999/07/12 04:18:26  daniel
 * Initial checkin
 *
