+Synopsis:        Maintaining an equivalence relation implemented as union-find using STT.
+Description:
+  This is an implementation of Tarjan's Union-Find algorithm (Robert
+  E. Tarjan. "Efficiency of a Good But Not Linear Set Union
+  Algorithm", JACM 22(2), 1975) in order to maintain an equivalence
+  relation.
+
+  This implementation is a port of the /union-find/ package using the
+  ST monad transformer (instead of the IO monad).
