    00078  * Changed GEOSException hierarchy to be derived from std::runtime_exception.
    00079  * Removed the GEOSException::toString redundant method (use ::what() instead)
    00080  *
    00081  * Revision 1.1  2006/03/09 16:46:49  strk
    00082  * geos::geom namespace definition, first pass at headers split
