Covariance: fix using Hessian Matrix in post-process #185

Currently, scipy does not always return errors. See #149 Try quick fix: take auto-derivative

@Arafraza (David Carroll) is going to help out with the Hessian matrix covariance method for his final project for his "Computational Physics" course.

Unfortunately David's exercise showed that the canonical packages to estimate the Hessian with our model function are very slow: many hours to run. So possibly a dead end. Will leave open in case we have any other thoughts.

I'm closing this since it hasn't panned out.
