maintaining an equivalence relation; profiling libraries

  This is a Haskell 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 package provides a library for the Haskell programming language, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
