public interface EdgeModel
An edge is an object that is contained by a graph and connects nodes. An edge has a "head" and a "tail" as if it was directed, but also has a method isDirected() that says whether or not the edge should be treated as directed (e.g. should there be an arrow drawn on the head). An edge has a semantic object that is its semantic equivalent in the application and may have a visual object which is its syntactic representation in the user interface.
