Disable ROSS output

[JohnPJenkins]

A command-line argument, --no-ross-output or similar, that disables the pre-run (timestamp, ROSS revision) and post-run (statistics) ROSS output would be great to have. That way, it's much easier to handle sims that e.g., dump their own data to stdout. Typically (for me at least), the ROSS output is best for debugging/tuning the simulation under various scenarios - it doesn't need to hang around for the subsequent "production" runs.

Do you still want the start/ending simulation messages and progress messages?

[JohnPJenkins]

Preferably not - ideally, with this option stdout would be completely unused by ROSS (with stderr being used for warning/error reporting).

hackathon - people want to post-process output via tw_output and piping. Suppressing ross output would be very helpful in this case.
