Make the reproducibility testing script work with the new GenericExtrapolationExample
There have been quite a lot of changes in the test framework recently, and in particular in the GenericExtrapolationExample. Some of these changes violated the expectations of my automated reproducibility testing script. So I updated it accordingly.
If you want to try it out, the new syntax is like this:
./testReproducibility.sh GenericExtrapolation ExtrapolationCharged ExtrapolationNeutral
