* --- Changelog
* 2.031: Some updates to the OptimizerFactory. Review of the MatlabInterface with adding an own options structure.
* Better access to the EvAClient, which now may have a RemoteStateListener added monitoring the optimization run.
* 2.030: Added an EnumEditor to access enums easily through the GUI, which will replace SelectedTags sometimes.
* IPOP-ES and RankMuCMA mutator have been added lately (wow!).
