Undirected edge handling #13

Closed skynx closed 6 years ago

skynx commented 6 years ago

Undirected edges did not behave as expected; by putting the undirected edge in the vertex-pair table for both endvertex orders, expected behavior was obtained. This change does not break the existing tests, but isn't checked by further tests.
