Gauss-Newton and Conjugate-Gradient optimization

This code implements a Gauss-Newton optimization of objective functions that can be iteratively approximated by quadratics. This approach is particularly appropriate for least-squares inversions of moderately non-linear transforms. You will also find code for conjugate-gradient and line-search optimizations.
