Haskell monad transformer library; documentation

 Haskell 98 part of a monad transformer library, inspired by the paper
 "Functional Programming with Overloading and Higher-Order Polymorphism",
 by Mark P Jones, in Advanced School of Functional Programming, 1995
 (http://web.cecs.pdx.edu/~mpj/pubs/springschool.html).
 This part contains the monad transformer class, the concrete monad
