Checkpont on radar unit test.

Task @T62 : There are still invalid results, but this version at
least improves transparency to the process. With luck, and perhaps
some congnitive surgery, I can resolve this in the next few days.
Checkpoint on the radar unit test.

Task @T62 : Much better, but still not perfect. Corrected some
errors in unit test object setup (no mass, overlapping positions)
and now we are getting good data for game cycles > 1. Unfortunately
the data at turn one is still crap, so I have more work to do.
