e4f51fea68 Switch to non-deprecated String functions
Use of String.*_ascii non-deprecated versions.

NB: Heptagon becomes available only for Ocaml versions >= 4.03.0.

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"

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).

f3d34f57d1 Abstraction of integers for Sigali
Correction of abstraction for Sigali: integer equations comprising no
integer variables should not be abstracted

f696203eb1 Bug in sigalimain
Bug correction: code generation to sigali for stateless nodes

=> stateless nodes handled like stateful nodes, if not in pervasives.

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).

2be4e287b9 Take into account the -nosink option in Sigali
Corrected bug: do not suppress the last state
variable when -nosink is on.

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).

2956002f85 Correction and simplification of the sigali pass
Added a "Contracts" pass, after inlining, taking care of the
contracts of the nodes called in the body of a node. This pass
"inlines" the code and assume/guarantee parts of these subcontracts.

The "Sigali" pass both generates the sigali ("z3z") code and add the call to
the controller (which is a node generated further by the sigali tool).
Therefore this pass has been included into the mls compiler, and removed
from the targets (a "z3z" dummy target has been kept for backward compatibility
reasons).

04b8853a1d Added a new reinit operator
It has type:
reinit: t at r * t -> t at r

It can be used to put a constant value in a 
location.
