module PatriciaSet:sig..end
Patricia trees are balanced binary search trees whose elements are
integers. These trees can be very efficient since navigating the
each tree uses only specific bits of the elements value. They
have O(w) worst case running time for the mem, add, remove
where w is the number of bits in an integer, but typically run in
O(log n) time for most inputs. Because, Patricia trees never need
to be re-balanced, union, inter, and diff can be much faster
than ordinary balanced trees, but still may take O(n+m) in the
worst case.

Reins.PatriciaSet.MonoSet module, except it also provides
the gen function.
