    00129  * $Log$
    00130  * Revision 1.4  2006/04/11 11:16:25  strk
    00131  * Added LineString and LinearRing constructors by auto_ptr
    00132  *
    00133  * Revision 1.3  2006/04/10 17:35:44  strk
    00134  * Changed LineString::points and Point::coordinates to be wrapped
    00135  * in an auto_ptr<>. This should close bugs #86 and #89
    00136  *
    00137  * Revision 1.2  2006/03/24 09:52:41  strk
    00138  * USE_INLINE => GEOS_INLINE
    00139  *
    00140  * Revision 1.1  2006/03/09 16:46:49  strk
    00141  * geos::geom namespace definition, first pass at headers split
    00142  *
