AList        -  association lists
UTerm        -  data type of terms
Subst        -  substitutions
Unifier      -  specification of unification and conditions for 
                correctness and termination
Unify        -  the unification function

To load, type use"ROOT.ML"; into an Isabelle-HOL that has TFL 
also loaded.
