Detailed Description

The circuit constraint is defined on a graph where the arc presence are controlled by literals. Each arc is given by an index in the tails/heads/literals lists that must have the same size.

For now, we ignore node indices with no incident arc. All the other nodes must have exactly one incoming and one outgoing selected arc (i.e. literal at true). All the selected arcs that are not self-loops must form a single circuit. Note that multi-arcs are allowed, but only one of them will be true at the same time. Multi-self loop are disallowed though.
