        I re-factored GaussNewton so the linear least squares solver is pluggable, and improved the efficiency of the existing implementations. If we create an interface for solving a linear least squares problem then users could provide their own implementations.

        I created a patch for each commit in my tree. Let me know if you would like them in a different format.
