first part using arc-fitting

[Boltz]

Completed my first part using arc-fitting today. A few random rapids, but overall very good. This was an excellent application for arc-fitting.

Didn't push it, just let the old Multicam glide along at 3 IPS.

The next release should have much better arc output than the current one. I've been using it a little for real jobs and have had good luck with it but I've also been able to get a good feeling for what to improve.

Thanks for the feedback.
