disabled variables appSetting & observedChunk in the
OverlayTopologyDonet.ned
used controlInfo->getDestAddr() instead of getNodeAddress()
not to output nHolder to reduce output log, easier to debug other
modules
disabled assert(inEdgesCtr[to] <= numStripes); <-- might have problem
later on
wrote edge list to file
removed observedChunk, added outputFilename to the Donet.ini
