 * $Log$
 * Revision 1.4  2006/05/04 15:49:39  strk
 * updated all Geometry::getDimension() methods to return Dimension::DimensionType (closes bug#93)
 *
 * Revision 1.3  2006/04/28 10:55:39  strk
 * Geometry constructors made protected, to ensure all constructions use GeometryFactory,
 * which has been made friend of all Geometry derivates. getNumPoints() changed to return
 * size_t.
 *
 * Revision 1.2  2006/03/24 09:52:41  strk
 * USE_INLINE => GEOS_INLINE
 *
 * Revision 1.1  2006/03/09 16:46:49  strk
 * geos::geom namespace definition, first pass at headers split
