00080  * Revision 1.2  2006/03/27 16:02:34  strk
00081  * Added INL file for MinimalEdgeRing, added many debugging blocks,
00082  * fixed memory leak in ConnectedInteriorTester (bug #59)
00083  *
00084  * Revision 1.1  2006/03/17 13:24:59  strk
00085  * 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).
