Base implementation of Set.
This class provides a base implementation of a Set that depends only
on the abstract members: add, contains, lookup, remove,
iterator, length and toSet.
Some of the methods assume that toSet creates a modifiable set.
If using this base class for an unmodifiable set,
where toSet should return an unmodifiable set,
it's necessary to reimplement
retainAll, union, intersection and difference.
Implementations of Set using this base should consider also implementing
clear in constant time. The default implementation works by removing every
element.
