package lustre-v6

Split the equations of a node into several ones, in such a way that there is only one operator per equation.

We also split tuples. For example, the equation:

(a, b, c) = (1, 2, 3) -> titi(x);

is splitted into 4 equations:

a = 1 -> _v1; b = 2 -> _v2; c = 3 -> _v3; (_v1, _v2, _v3) = titi(x);

The node local_env is provided so that we can update its table, as we add some fresh local variables during the code transmation.
