  59  * $Log$
  60  * Revision 1.14  2006/03/09 16:46:49  strk
  61  * geos::geom namespace definition, first pass at headers split
  62  *
  63  * Revision 1.13  2006/03/06 19:40:47  strk
  64  * geos::util namespace. New GeometryCollection::iterator interface, many cleanups.
  65  *
  66  * Revision 1.12  2006/03/03 10:46:22  strk
  67  * Removed 'using namespace' from headers, added missing headers in .cpp files, removed useless includes in headers (bug#46)
  68  *
  69  * Revision 1.11  2006/02/23 11:54:21  strk
  70  * - MCIndexPointSnapper
