* $Log$
* Revision 1.23 2006/04/03 15:54:34 strk
* - getArgGeometry() parameter type changed from 'int' to 'unsigned int'
* - Added port informations
* - minor assertions checking
* - minor cleanups
*
* Revision 1.22 2006/03/21 21:42:54 strk
* planargraph.h header split, planargraph:: classes renamed to match JTS symbols
*
* Revision 1.21 2006/03/02 14:34:43 strk
* GeometryGraphOperation::li made a non-static member, and not more a pointer
*
* Revision 1.20 2006/02/27 09:05:33 strk
* Doxygen comments, a few inlines and general cleanups
*
* Revision 1.19 2006/02/19 19:46:49 strk
* Packages <-> namespaces mapping for most GEOS internal code (uncomplete, but working). Dir-level libs for index/ subdirs.
