Robust nonlinear least squares fit of exact equation of circle to xy data

You are now following this Submission

Iterative, robust fit of the exact equation of a circle to xy data. Outliers are identified based on multiples of current standard deviation and "set aside". The interative solution proceeds until there are no remaining outliers. Returns xo,yo,R, terminal outlier criterion, and residuals vector.
