Description

When stopping the genetic minimizer, we may end with a fit that is much worse than what had been attained a few steps earlier.

Therefore, after each fit step we should update a register that holds the parameters and the chi2 (or whatever) of the best fit attained so far. Upon stop, parameters should be set to that value.
