[ANN] CircleFit.jl

This is a simple package to fit a circle to points in a plane.
Currently, there are 3 methods implemented (Kasa, Pratt, Taubin).


To expand the package a bit I want to to include some methods provided by StatsBase like dof, residuals, coef, rss.

I was thinking of introducing a new return struct which can handle those methods.
Is there a common naming scheme or procedure on how to do handle for results?

To also implement fit and fit! I think I need a struct to represent the model itself, not only the results. Are there any good examples on how to implement a RegressionModel?

The new version is currently developed in the statsmodel branch.

Just registered version 0.2, which now uses a StatsBase.RegressionModel like interface.
