// Now we can have multiple 'instances' of traffic lights that all share the same FSM:
var light1 = { location: "Dijsktra Ave & Hunt Blvd", direction: "north-south" };
var light2 = { location: "Dijsktra Ave & Hunt Blvd", direction: "east-west" };

// to use the behavioral fsm, we pass the "client" in as the first arg to API calls:
vehicleSignal.pedestrianWaiting( light1 );

// Now let's signal a pedestrian waiting at light2
vehicleSignal.pedestrianWaiting( light2 );
