111 * $Log$
112 * Revision 1.2 2006/03/27 16:02:34 strk
113 * Added INL file for MinimalEdgeRing, added many debugging blocks,
114 * fixed memory leak in ConnectedInteriorTester (bug #59)
115 *
116 * Revision 1.1 2006/03/17 13:24:59 strk
117 * 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).
