Description

For fitting reflectometry data, it might be useful to stop the genetic minimizer when qualitative agreement is reached, and then switch over to Levenberg-Marquardt. Currently, this is cumbersome because one needs to parameters one by one from constraint to free.

As long as Levenberg-Marquardt does not allow constraints, we should simply ignore the parameter limits settings. In the GUI, disable them.
