Checks that nodes in .env files are contiguous as the code suppose they are.

Version-Log:

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.

Version-Log:

Add support to handle numerical contraints. The numerical stuff is
untested, but the boolean part works as before.

source/rnumsolver.mli:
source/rnumsolver.ml:
    New files implementing a numeric solver based on intervals.

source/*.ml:
    Change the var_type type from a string to a sum type containing
    the lower and upper bounds of numeric domains.

    Do not maintain a var_name to index correspondance, but a formula to
    index one. This is to be able to handle numerical constraint in bdds.
    This field is not set at init time anymore, but in formula_to_bdd.

    Add <>, <, and <= to the type of formula.

The solution number counting function was wrong.

the number of solution numbers.

Various fixes so that lurette can be build from scratch.

Project-Description: Lurette

Version-Log:

gen_stubs.ml:
    Updates the stubs files (lurette_stub.ml, sut_stub.c,
    sut_idl_stub.idl, oracle_stub.c, oracle_idl_stub.idl) iff they have
    changed to avoid unnecessary recompilations.

Makefile:
    Minor cosmetic changes.

wtree.ml,mli:
env.ml:

    Also remove a loop in the dependencies that was confusing
    ocamldot (but how could it work before with that loop ?). To do that,
    pass Solver.is_satisfiable as a argument of Wtree.choose_n_formula so
    that Wtree does not depend on Solver anymore.

Project-Description: Lurette

Parent-Version:      0.25
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:
    rename arcs_inputs_loc into nll_inputs_loc.

Version-Log:

Add a bdd-based boolean solver to draw inside formula.

Also remove several module opening and use explicit module
qualification instead

lurette.ml:
env_state.ml:
    Define a function in env.ml to get the list of input and outputs var names
    and use it in lurette.ml

env_state.ml:
    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.
