Edge<V, E> class
abstract
An edge withing a graph connects a source and a target vertex.
Edges are typically ephemeral objects and are only created on demand.
There are two types of edges, DirectedEdge and UndirectedEdge. The
only difference is that undirected edges consider source and target
interchangeable for comparison operations. The value is never used
for comparison.
