00095  * Revision 1.4  2006/04/11 11:16:25  strk
00096  * Added LineString and LinearRing constructors by auto_ptr
00097  *
00098  * Revision 1.3  2006/04/10 17:35:44  strk
00099  * Changed LineString::points and Point::coordinates to be wrapped
00100  * in an auto_ptr<>. This should close bugs #86 and #89
00101  *
00102  * Revision 1.2  2006/03/24 09:52:41  strk
00103  * USE_INLINE => GEOS_INLINE
00104  *
00105  * Revision 1.1  2006/03/09 16:46:49  strk
00106  * geos::geom namespace definition, first pass at headers split
