**********************************************************************
* $Log$
* Revision 1.2 2006/06/12 16:57:51 strk
* Removed unused parameter warnings
*
* Revision 1.1 2006/01/31 19:07:35 strk
* - Renamed DefaultCoordinateSequence to CoordinateArraySequence.
* - Moved GetNumGeometries() and GetGeometryN() interfaces
* from GeometryCollection to Geometry class.
* - Added getAt(int pos, Coordinate &to) funtion to CoordinateSequence class.
* - Reworked automake scripts to produce a static lib for each subdir and
* then link all subsystem's libs togheter
* - Moved C-API in it's own top-level dir capi/
* - Moved source/bigtest and source/test to tests/bigtest and test/xmltester
* - Fixed PointLocator handling of LinearRings
* - Changed CoordinateArrayFilter to reduce memory copies
* - Changed UniqueCoordinateArrayFilter to reduce memory copies
* - Added CGAlgorithms::isPointInRing() version working with
* Coordinate::ConstVect type (faster!)
* - Ported JTS-1.7 version of ConvexHull with big attention to
* memory usage optimizations.
* - Improved XMLTester output and user interface
* - geos::geom::util namespace used for geom/util stuff
* - Improved memory use in geos::geom::util::PolygonExtractor
* - New ShortCircuitedGeometryVisitor class
* - New operation/predicate package
*
* Revision 1.13 2004/07/19 10:35:23 strk
* bigtest.h moved to local dir
*
* Revision 1.12 2004/07/02 13:28:26 strk
* Fixed all #include lines to reflect headers layout change.
* Added client application build tips in README.
*
* Revision 1.11 2003/11/07 01:23:42 pramsey
* Add standard CVS headers licence notices and copyrights to all cpp and h
* files.
