      Recursively check in the global normalisation hash table whether the · 86748961

      type has already been normalized. Without this patch, in the following usage:
      
      norm(T1, delta)
      norm(<a>[ T1 ], delta)
      
      the fact that T1 has already been normalized against some delta is not taken into
      account while normalizin <a>[T1].

      Improve the complexity of constraint normalisation by using a hash · 7932c071

      table instead of a 'recursion set' like in the paper.  The hash table
      is tricky:
      
       - its keys should be both the type we are normalizing and
      delta
      
       - we should store a flag together with the constraint set, indicating
      whether the computation of the normalization for the corresponding
      type has finished. If it has, we can use the associated constraint set
      instead of CS.sat and stop recursion. If it has not, we can return
      CS.sat (like the previous base case).
      
      We also update the test case files to check that everything is in order:
      
      - part2.cd has been rewritten to make use of the new syntax and remove
        the red-black trees examples that are now in a separate file
      
      - red-black.cd is a fully typechecking file
      - rb-fail.cd has the type definition and the wrong balance function.

      Make fresh variables really fresh · c9ad3e5c
      Pietro Abate authored
      Add a global variable table, so when we call "Var.mk id" twice, the
      same variable is returned and when we call "Var.fresh v" we always
      return a truly globally fresh variable.
