Added standalone support for multiple streams. Added a logging infrastructure. Added a trivial application for testing purposes (dumb-client and dumb-server). Added the capability for running the standalone stub with a tcpdump replay. Added support for changing buffer sizes. Added shell files for experiment management, reset.sh which is to reset the dummynet settings between runs and run-iperf.sh which encapsulates a set of options to iperf.
