Fast Elitist Non-Dominant Sorting Genetic Algorithm.

Note that this class does not do the sorting per se, but the sorting of it worth_std::vector will give the right order

The crowding distance is calculated as the sum of the distances to the nearest neighbours. As we need to return the penalty value, we have to invert that and invert it again in the base class, but such is life, sigh
