improve detector to handle longer cycles (triple,quadruple..)

[gmmoura]

So we recently found that longer cycles are possible and resolvers get stuck in them too... like a->b->c->a.

We need to verify if cycleHunter can detect those, and if not, improve it.

I have an idea for that, and some code implemented in parallel with CycleHunter that finds cycles of any length. I can create a branch with that code for you to see and test.

sure, please go ahead, @seb-at-nzrs :)
