source/env_state.ml
   Fix several bugs in the way automata run in parallel were handled.
   (actually, i knew that this feature was broken).

   Also add support to handle cases where the same variable has
   several min (take the max), max (take the  min), alias, default,
   init (abort) option values.
   I am not sure if i should authorize that for min and max though.

Parent-Version:      1.15
Version-Log:

source/lucky.ml:
   Fix a bug (revealed by Claude) that was appering
   when several automata were run in parallel: the symptom
   was that several values were generated for some outputs.
   The bug was due to the fact that the order of the list
   of paths (used to, among other things, to retreive the
   current node) was wrong: the consequence was that the automata
   order was different from the one of expected variables,
   hence it was also generated values for those extra variables
   for automata where it was not necessary.

source/lurette.ml:
   launch the oracle checking for the outputs of the step also...

test/*:
   Add non reg test for that bug and the previous one.

   Raise No_numeric_solution if the polyhedron volume
   is smaller then epsilon.

   Recompile the Lustre program if necessary.

source/gen_fake_lutin.ml:
   Declare the variables in the same order as in the sut program.

source/store.ml:
source/polyhedron.ml:
   Fix a bug signaled by Claude where lurette was aborting
   when solving integer constraints. It was due to a bad
   implementation of is_point_in_poly which did not
   convert floats to ints when necessary (this bug was introduced
   rather recently when i provided my own version of
   is_point_in_poly... and of course i have non reg-test
   with integer constraints...).

Project-Description: Lurette

Parent-Version:      1.7
Version-Log:

Implement a new drawing policy in polyhedron.

The idea is to base the base (which is not so expensive), and to draw
in othogonal hypercube that is as small as possible until a point in
the polyhedron is found.  However, it may happens in high dimension (>4)
that the volume of the cube is much bigger. In that case, after a few tries,
i call the old (unfair) method.

polyDram.ml/mli:
   new module containing all the thing related to the drawing inside
   a convex polyhedron.

   Give up the idea of random walk (not clear what should be the default
   step and length in big dimension).

   The same as bddd, but taking polyhedron volume into account.

source/bddd.ml:
   It is useless to store both bdd and not bdd, because it is just
   so easy to recompute the sol nb of not bdd (by switchinf the
   pair of sol numbers!).

source/lurettetop.ml:

   use map instead as hashtbl for the range base store.

   leads to clearer code (no need to copy the store, which was particularly
   bad when done outside that module...), and is as efficient.
