...
The base algorithm transparently ignores edges, but only if
the graph contains at least 1 edge with positive weight.
If ALL edges have negative weight, dual variables may be
initialized to negative values which leads to failure.

Unit tests ported over from old code
...
These tests probably don't provide good coverage for the new code.
But it's a start.
