Fix conditionaly compiled code, that contained type errors.

Improve the debugging of the unify step of the tallying. Fix a bug where substitutions were applied in the wrong order, yielding partially empty types.

Move the bool.ml{,i} files in types/ where they belong.

Implement some semantic simplification of BDDs. This fixes the exponential beahviour during the typing of the application of flatten.

Refactor the Bool/BoolVar code so that they share the same interface. Give access to the underlying atom module in BoolVar.

Improve pretty printing of Bdds and add debug directive to interactively inspect the internal representation of types.

Seal the representation of SortedList.Make(X).t (by making the type private). Expose Var.Set as a SortedList.S

Perform a more aggressive memoization of substituted types and register the name if the original type was named.
Make the pretty-printer re-entrant.

- type variables are now correctly parsed as patterns
  and not as expressions

- Add a new module Var that contains all the type variables
  related machinery

- Remove old functions and unit tests about BoolVar of only
  variables, since now variables are always stored associated
  with one or more kinds

- revert a few chances I did before in the code
- add new unit tests functions for the Tallying problem
