    00085  * $Log$
    00086  * Revision 1.2  2006/03/27 16:02:34  strk
    00087  * Added INL file for MinimalEdgeRing, added many debugging blocks,
    00088  * fixed memory leak in ConnectedInteriorTester (bug #59)
    00089  *
    00090  * Revision 1.1  2006/03/17 13:24:59  strk
    00091  * 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).
