a0e97b82ea CtrlNbac backend: systematic sink state, outputs as local variables
Changes in CtrlNbac back-end :
- systematic sink state, only in ctrln code
- sink state "ok" removed (useless as was coded)
- no sink state in minils code
- outputs in ctrln are local variables, no longer state variables

d8d24ffd95 Handle modularity/several controllers by module
* Several controllers by module : added option "-m <Module>" in ctrl2ept

Generate controllers for each node of one module in <module>_controller.ept

* Types of <Module> no longer moved to <Module>_controller

* Added "_types" suffix for type dependencies for C target

3dfbeffeb6 Added syntax for reachability and attractivity in contracts
Contracts can now comprise a list of objectives (in any order).

One objective can be (e being a Boolean heptagon expression) :
- invariance, with the syntax "enforce e"
- reachability, "reachable e"
- attractivity, "attractive e"

307f3d8418 Controllable-Nbac import&export now support relocation of alias types.
- Controllable-Nbac export (CtrlNbacGen): correct handling of float
  expressions, as well as alias types;

- Controllable-Nbac controller importer (CtrlNbacAsEpt): Declaration
  of enumerated types and aliases that are relocated to controller
  modules is now performed based on the interface.  Dependencies
  between type aliases are also taken into account now;

- ctrl2ept tool: correct loading of pervasives module.

39aa0e13c1 Ugly fix for handling enumerated types when exporting to Controllable-Nbac.
To avoid cyclic module dependencies (that show up when trying to
compile, e.g, the generated C code), enumerated types declared in the
main program are now "moved" into the module containing the generated
controllers.

be21bf31d8 Insertion of call to controller(s) when exporting to Controllable-Nbac node.
To enable recovery of parameter and output ordering by `ctrl2ept', the
Controllable-Nbac generation procedure now declares a new module
dedicated to the encapsulation of the controller functions yet to be
synthesized.

Handling of type declarations are probably buggy.

e885f82e00 Bug correction/feature adding: abstraction within contracts
Allowing additional inputs from abstractions within contracts. Thus,
calling non-inlined subnodes is allowed, as well as operations on
non-Boolean inputs or states (in contracts).

- Stripped portions of `myocamlbuild{,_config}.ml' that seem useless
  when `-use-ocamlfind' is passed to ocamlbuild.

  documentation by merging interface and implementation files.

8aeab651ce First draft for Controllable-Nbac format generation.
- CtrlNbac: new module for internal representation and output code for
  Controllable-Nbac format;

- CtrlNbacGen: translation into Controllable-Nbac of Minils nodes
  necessitating controller synthesis; the insertion of calls to
  controllers is not yet done, and the nodes are left unchanged.

8497bafa2e Minor but correction in sigali output.
- Translation to z3z now evaluates constant expressions instead of
  abstracting them. This non-feature could cause "false" synthesis
  failures due to non-translatable yet constant expressions possibly
  introduced by tomato (or manually), for instance `not false' in node
  `n' bellow:

    node n (a: bool) returns (ok: bool)
      contract assume true enforce ok with ()
    let
      ok = a or not false;
    tel

9db97de879 Bug correction in `Sigalimain.translate_eq'.
- In Sigalimain: untranslatable non-boolean expressions should not be
  added as inputs of the controller.

- Avoided some compiler warnings in the same module (with OCaml ≥ 4).

ef536f412d Added option -nosink (CS optimisation)
The -nosink option suppress the sink state of sigali equations.

This optimizes the controller synthesis, but work only
when the synthesis objective instantaneoulsy depends only
on the current state (and not on current inputs).
