This PR moves the logic specific to nonlinear least squares problems from NonlinearOptimizer to the NonlinearLeastSquares subclass. The base class now only provides some default info tracking methods, and defines an abstract method called _error_metric(), which can be used instead of the previously hardcoded sum of squares.
