Swarming implies that a single instance of the kripke
structure (or product) will be explored by diffrent threads
with their own exploration order. Most of the modification
aims to have a thread safe kripke structure.

In order to reuse the computation of the
intersection between kripke and twa efficiently,
we use template inheritance through the
"mixin templates" technique.
