coming to you late in the evening and talking French.

Sorry for the previous commit, submitted by accident.

Interface consistency is god.

Register : Essaie d'utilisation de WeakHashtbl mais comme 'a registered est polymorphe il ne peut instancier t

the underlying term/fmla is not changed

In the majority of cases, it is just None. 

Update the whole shebang to use the new core modules

- env-dependent functions are not needed any more

- the member function [clear] is not needed, it is
  the responsibility of Driver to drop and recreate
  transformations whenever desirable. 
  
  (François, don't get mad, please :)

Not only Theory, but also Task and Transformation 
do not need to depend on environment. Moreover,
we don't have to track the clone history in tasks.

The only thing we need to do, is to provide three
registration functions in Driver, namely:

  val register_transform : string -> (unit -> task_t) -> unit
  val register_transform_env : string -> (env -> task_t) -> unit
  val register_transform_clone : string -> (env -> clone -> task_t) -> unit

and then another three for task_list_t.

Then any particular transformation that is going to depend
on environment or clone_history, must register itself via
the appropriate registration function. It will be the
responsibility of Driver to recreate the transformation
for every new environment and/or clone history. It will
be easy, given that both [env] and [clone] are physically
comparable and provide a unique tag.

Thus, the generic interface provided by Transform can be
completely independent on [env] and [clone].

This commit implements the proposed interface of Task
and moves the environment stuff into a separate module.

ajout de la transformation split_to_cnf qui met en une forme presque cnf. Une CNF où on garde la position des négations et implications. L'interet est au moins pour la visualisation. On retrouve (normalement) une cnf simplement en poussant les négations.

main.ml : possibilité de mettre specifier plusieurs theories ou buts
split_goals : ajout d'un argument supplémentaire pour ne selectionner que certains buts.
