      Implement the polyhedron drawing primitives.
      
      source/util.ml.in:
         Change my_string_of_float so that it truncates floats 4 digits after the
      dot.
         The rational is that, for testing, we do not care the extra precision and
         too much precision may kill Polka. This precison ougth to be a parameter
         though.

         Do not explicitely handle dis-equalities but transform it using
         not and = instead. The rational for this change is to avoid code duplication
         (which was buggy !!!), but also to allow handle dis-equalities with
         the optimized algorithm I had for eqalities (for free) !

      Various minor fixes in the documentation
      
      + Use a version of ocaml-3.06 that has been configured with -no-curses,
      which make things sligthly slower, but that avoid the need to find
      the curses lib...
      
      source/ne.ml:
      source/*.ml:
         Ne.find now returns an option value instead of raising a Not_found
         exp, which was not trap in some circumstances...
      
      source/ne.ml:
         Also, fix a couple of bugs where the code was supposing (falsely)
         that the constant (empty string) was always in the Map.

      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.

      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).

      Version-Log:
      
      Re-arrange the code so that lurette_stub.ml is not called by all the
      modules of lurette to avoid that everything is recompiled each time a
      new sut is used. To do that, lurette nows only manipulates list of
      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
      
      Plus a few cosmetic change:
      
      show_env.ml:
      lurette.ml:
          prints the previous nodes in green environment.ps
      
      lurette.ml:
