Generic Function Other-Vertex (2 methods)

( other-vertex < edge > < value-or-vertex > )

Part of:

package cl-graph

Assuming that the value-or-vertex corresponds to
one of the vertexes for edge, this method returns the other vertex
of edge. If the value-or-vertex is not part of edge, then an error
is signaled. [?? Should create a new condition for this]
