         Put back the verteces draw. It was not such a great idea to remove
         after all...
      
         Also change verteces into vertices (oops...).

      Version-Log:
      
      Prepare things for the next change (which will try to handle equalities
      smartly).
      
      source/solver.ml:
      source/rnumsolver.ml:
         atomic_formula do not need both < and > (ditto for <= and >=).
         Indeed, I just need to take the opposite, and everything is fine.
         One advantage is that there are less cases to handle. But the key
         advantage is that it make the representation of constraint normal,
         which is important at least when I will try to detect equalities.
      
         Also add a subst list and constraint list fields to the store
         that will ebe used in the forthcoming change. They will resp.
         be used for removeing a dimension when an equality is encountered
         and to delay constraint with more than one variable.
      
      source/constraint.ml,mli: (new files)
         Move there from formula.ml everything that is related to the internal
         representation of constraints.
      
         Also change the name of atomic_formula to linear_constraint, which is
         more informative.

      Version-Log:
      
      wtree.ml,mli:   (deleted)
      automa.ml,mli:  (new files)
      control.ml,mli: (new files)
      
         Replace the [wtree] module by an [automata] module, that basically
         does the same job, but in a different way. Namely, it no more uses
         the [wtree] DS to use [graph]s instead.  Indeed, the product of
         wtrees introduces some problems, in particular to ensure its
         correctness wrt to the automata run concurrently. Now, everything a
         dead-simple wrt product: we simply perform a quasi-classical automata
         product (well, at least, much closer from a classical product, cf
         paper).
      
         The way loop counters are handled has also changed. Now, counters are
         handled via expressions of a simple arithmetic language that
         basically lets one initialise a variable to an exact or a random
         value (uniform or normal draw) and decrement it. Arcs are now
         labelled by a formula plus 2 expressions of that mini-language (no
         more weigth nor cpt_init stuff). The 1st expression is evaluated
         during the draw, basically performs any operations on counters, and
         returns a positive int that is used as the formula weigth. The second
         expression (a kind of post-condition) is evaluated if its arc is the
         one that has been elected to perform the step.
      
      At several locations long lines (< 80) are reindented.
      
      parse_env.ml:
         In the ima format, IfThenElseExpr becomes IfThenElseNum.
         Also, parse list more cleanly.
      
      graph.ml,mli:
          Add a function that test whether a transition is in the graph.
      
          Do not sort list of transitions anymore (what was the point?).
          Also do not sort nodes in any way.
      
      show_env_env.ml,mli:
         Abstract away nodes and arcs data types (so that I can display
         Automata graphs). rename generate_env_graph into ima_to_dot.
      
      lurette.ml:
      ima_exe.ml:
         Fix a bug where bbd table were filled by asserted non regression expr.
      
      lurette.ml:
         Fix a bug where incorrect data was sent to sim2chro (ie, the output of the
         previous step instead of the ones of the current step.
      
      env_state.ml:
      solver.ml:
      gne.ml:
         Fix a performance bug where I was storing formula indexes even if
         they were depending on inputs or pre, which is stupid as they generally
         won't be used again. In order to fix that, I introduced  new
         atomic_formula <-> indexes table to stote the ones that do not depend
         on inputs apart. It was also necassery to propogate the <<depend on pre>>
         flag inside Gne.gn_expr (which i renamed Gne.t BTW).

      Add a new module gne.ml that provides a garded normal expressions
      data structure that is used to handle if-then-elses.
      
      Also introduce a new field to env_state called bdd_tbl_global which
      is used to cache the result of formula_to_bdd for bdds that do not
      depend on pre nor input vars. The field bdd_tbl which cache the other
      reults is now cleared at each step because it is useless to store results
      that depends on pre and inputs.

      Make sure that n formula are drawn when even numeric failure occurs.
      To do that, I recursively call draw_n_p_formula until the required
      number of outputs have been generated.
      
      Also fix a bug where my code was not handling cases where several
      formulas corresponding to the same origin and target nodes (Lutin
      probably won't generate such arcs explicitely, but it does
      implicitely via epsilon transitions). The fix consist in adding
      formula in wtree types instead of maintaining a table of formula
      indexed by node list pairs. The env_state.formula_table is thus no
      longer needed.

      Re-arrange the code so that lurette_stub.ml is not called by all the

      substitutuions instead of tuples (as only lurette_stub knows the size
      of the tuples).
      
      Also fix two bugs along the way:
          o wtree.ml: Random.int n draw between 0 inclusive and n *exclusive* !
          o wtree.ml: in wtree_product, make sure that I do not unsort list of nodes
          o solver.ml: in draw_in_bdd, I was tossing up the top var of the formula
            instead of tossing up the one of the support

          Add several fields to the env_state structure:
          * node_to_file_name: to be able to retrieve the list of vars that
            ougth to be generated from a list of nodes (Indeed, some vars
            that should be tossed up do no necessarily appear in formula; and
            once the whole bdd has been traversed for the draw, we need to be able
            to know what variable are still to be drawn).
          * var_name_to_index and index_to_var_name: to index output and local
            variable names. Indeed, the bdd library we use manipulates var as int,
            not string.
          * bdd_tbl: be cause transforming a formula into a bdd is expensive,
            we store the result of this transformation in a table.
      
          Define the var_names field as an Hashtbl instead of a list for homogeneity.
      
          Define functions that retrieve the list of input (resp output and local)
          vars from env_state to avois code duplication.
      
      env.ml:
          Initialize the new fields of env_state.
      
      util.ml:
      util.mli:
          Add a new function that computes the intersection of 2 lists.
      
      solver.ml:
          Implement a real boolean solver using bdds.

       Handle pre in formula and expressions. Also add (in
      green) the environment local vars in the sim2chro output.

      Now lurette can hanble multiple environements that can either be
      run as a product or in parallel.
