Simple functional ring type; documentation

 Simple functional bidirectional ring type in Haskell.
 .
 Given that the ring terminiology clashes with certain
 mathematical branches, we're using the term CList or
 CircularList instead.
 .
 This package provides the documentation for a library for the Haskell
 programming language.
 See http://www.haskell.org/ for more information on Haskell.
