created CTL simulators to send CTL command on and off and to receive CTL commands
really adding files this time!
Modified center finding to do a circle fit to chords. Unstable.
Non-uniformly distributed crossings on limb are inducing bias in center.
Tried averaging offsets to correct bias. Didn't work.
Implementing different paper. Coope 1993, J. of Opt. Theory. Center seems stable, radius fluctuates much more than previous method.
Added Cook distance measuring. Not sure what it changed.
Better preprocessor defines/comments and cleanup
