* $Log$
* Revision 1.9 2006/03/15 17:16:29 strk
* streamlined headers inclusion
*
* Revision 1.8 2006/03/03 10:46:21 strk
* Removed 'using namespace' from headers, added missing headers in .cpp files, removed useless includes in headers (bug#46)
*
* Revision 1.7 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 1.6 2005/12/07 23:36:49 strk
* standard indentation
*
* Revision 1.5 2005/11/16 22:21:45 strk
* enforced const-correctness and use of initializer lists.
*
* Revision 1.4 2005/11/07 12:31:24 strk
* Changed EdgeIntersectionList to use a set<> rathern then a vector<>, and
* to avoid dynamic allocation of initial header.
* Inlined short SweepLineEvent methods.
*
* Revision 1.3 2005/01/28 09:47:51 strk
* Replaced sprintf uses with ostringstream.
*
* Revision 1.2 2004/07/02 13:28:26 strk
* Fixed all #include lines to reflect headers layout change.
* Added client application build tips in README.
*
* Revision 1.1 2004/03/19 09:48:45 ybychkov
* "geomgraph" and "geomgraph/indexl" upgraded to JTS 1.4
*
* Revision 1.9 2003/11/07 01:23:42 pramsey
* Add standard CVS headers licence notices and copyrights to all cpp and h
* files.
