Comment(by abmasse):
Just some questions before I set this ticket to positive review.
Are `cardinality` and `number_of_subsets` the only functions that should
jump to the parent class?
Correct me if I'm wrong: the reason why the methods `find`, `union`,
`root_to_elements_dict`, `to_digraph`, etc. is that they are specific to
each data structure. In principle, they all should be in the parent class,
but be declared as "abstract", but this is not in the Python philosophy.
Does my understanding seems correct?
Alex
