* $Log$
* Revision 1.11 2006/03/17 13:24:59 strk
* opOverlay.h header splitted. Reduced header inclusions in operation/overlay implementation files. ElevationMatrixFilter code moved from own file to ElevationMatrix.cpp (ideally a class-private).
*
* Revision 1.10 2006/03/09 16:46:49 strk
* geos::geom namespace definition, first pass at headers split
*
* Revision 1.9 2006/03/03 10:46:22 strk
* Removed 'using namespace' from headers, added missing headers in .cpp files, removed useless includes in headers (bug#46)
*
* Revision 1.8 2006/02/19 19:46:49 strk
* Packages <-> namespaces mapping for most GEOS internal code (uncomplete, but working). Dir-level libs for index/ subdirs.
*
* Revision 1.7 2005/11/16 15:49:54 strk
* Reduced gratuitous heap allocations.
*
* Revision 1.6 2004/07/02 13:28:28 strk
* Fixed all #include lines to reflect headers layout change.
* Added client application build tips in README.
*
* Revision 1.5 2003/11/07 01:23:42 pramsey
* Add standard CVS headers licence notices and copyrights to all cpp and h
* files.
*
