private TestEdge edge(int startId, int endId) {
		return edge(v(startId), v(endId));

A test meant to exercise most of the code paths inside of {@link VisualGraphPathHighlighter}.
These tests are not validating the actual correctness of the path calculation, as that work
is being done by the various graph algorithm tests.
