PopulationFitnessView is package private, why?

There's some possible reuse of that class, but can't be even instantiated because it is package private. Any reasons for that?

It was only intended to be part of the evolution monitor component, which itself was fairly experimental. Being package private means I don't have to worry about breaking other classes that depend on it if I change it, but if you have a convincing reason to make it public I'm happy to consider changing it.
