Comment (by chaoxu):
It's fairly strange that filling in the SetSystem takes that long... I
will check if it can be optimized.
> If not enough, what exactly would suffice for your purposes? A method
component(e) (to compute the component containing e) and a method to
restrict all subsets to a given subset?
Yes. But instead of component(e), components() is enough, since we have to
iterate over all components if it's not connected.
