Detailed Description

Operates signal lights. changes the lights at a node. based on a state machine. engine creates states and simply cycles through them.

Assumes that the initial color of lights at a road determines the relationship of lights at that intersection. for example, in a normal intersection, the non-perpendicular road segments should have the same color - one pair green, the other red.
