    00138  * Revision 1.4  2006/04/11 11:16:25  strk
    00139  * Added LineString and LinearRing constructors by auto_ptr
    00140  *
    00141  * Revision 1.3  2006/04/10 17:35:44  strk
    00142  * Changed LineString::points and Point::coordinates to be wrapped
    00143  * in an auto_ptr<>. This should close bugs #86 and #89
    00144  *
    00145  * Revision 1.2  2006/03/24 09:52:41  strk
    00146  * USE_INLINE => GEOS_INLINE
    00147  *
    00148  * Revision 1.1  2006/03/09 16:46:49  strk
    00149  * geos::geom namespace definition, first pass at headers split
    00150  *
