Represents a directed edge in a graph connecting two vertices of type V. This implementation specifically models directed edges for graph structures, where the direction is indicated from a from vertex to a to vertex. The edge carries no additional attributes.
Retrieves the starting Vertex of this Edge. If this is an UndirectedEdge, white and black represent the nominal direction. Individual adjacencies can be based on a flipped version of an UndirectedEdge.

Attributes
Returns
the vertex where the edge originates (the "white" vertex).
