Multiple node pass

[blahami2]

Allow routing through a single node multiple times (for example when starting in an opposite direction, a route around has to be made, possibly returning to some of the nodes already visited)

Do so by changing nodes to states (vectors) of [node, incomingEdge/outgoingEdge (think about it!)]

Requires further analysis

[blahami2]

Impossible to route with turn restriction

• it does not just block the one important crossroad
• it creates an impenetrable "wall" around the target

[blahami2]

Node -> State

• node
• incoming edge

Done for all the algorithms
