Reverted changes to time format. Added a 'SENSOR_DETAIL' and 'SENSOR_COMPLETE" logging options. 'SENSOR' should now be used for high level information, 'SENSOR_DETAIL' should be used for medium level information, and 'SENSOR_COMPLETE' should be used for low-level information. If SENSOR_DETAIL logging is turned on, then SENSOR logging is also turned on. If SENSOR_COMPLETE logging is turned on, then SENSOR_DETAIL and SENSOR loggin is also turned on. All three of these levels use the 'SENSOR' prefix when outputting logging lines.

Added ewma for throughput. Various fixes. Various additional logging. Simplified saturation calculation and moved it to StateSensor

Many minor fixes. Still not quite functional. TODO: Move the rest of the networking code from stubd. Move measurement code from stubd.

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.
