Torperf should output circuit build times
The extra_data.py listener for TorPerf should be outputting circuit build times for research and analysis. I can help with this. It shouldn't be too difficult to do if we just add CIRC events to its EventListener.
The .extradata file format may change, which may or may not make some people sad. I'm not sure if anyone besides us is looking at those files though.
