Graph.Edge
Graph.Edges
only be .equals()
when they refer to the same actual edge in the graph.
Which edge this is does not change when the contained
user-defined object changes. In a multigraph, the
endpoints and contained user-defined object are generally
not sufficiently distinguishing characteristics.
Accepting the default implementation from
Object
, which uses reference equality, should
be preferred unless Graph.Edges
are lazily
created on demand.

Since it is mutable, the contained user-defined object
should not be used when computing the hash code.
