Removed SimpleGeometryPrecisionReducer capability * of changing Geometry's factory. Reverted Geometry::factory member * to be a reference to external factory. * * Revision 1.20 2004/07/05 10:50:20 strk * deep-dopy construction taken out of Geometry and implemented only * in GeometryFactory. * Deep-copy geometry construction takes care of cleaning up copies * on exception. * Implemented clone() method for CoordinateSequence * Changed createMultiPoint(CoordinateSequence) signature to reflect * copy semantic (by-ref instead of by-pointer). * Cleaned up documentation. * * Revision 1.19 2004/07/02 13:28:26 strk * Fixed all #include lines to reflect headers layout change. * Added client application build tips in README. * **********************************************************************/
