 * $Log$
 * Revision 1.14  2006/03/27 16:02:34  strk
 * Added INL file for MinimalEdgeRing, added many debugging blocks,
 * fixed memory leak in ConnectedInteriorTester (bug #59)
 *
 * Revision 1.13  2006/03/17 13:24:59  strk
 * opOverlay.h header splitted. Reduced header inclusions in operation/overlay implementation files. ElevationMatrixFilter code moved from own file to ElevationMatrix.cpp (ideally a class-private).
 *
 * Revision 1.12  2006/02/19 19:46:49  strk
 * Packages <-> namespaces mapping for most GEOS internal code (uncomplete, but working). Dir-level libs for index/ subdirs.
