> SSSP shows max int for path length for unreachable vertices. Unreachable
> vertices should probably be filtered out from the output table altogether.
> (See attached screen shot.) In its current form, this may have an impact on
> helper functions too though I have not looked yet in detail.
> This may also affect other modules too like APSP. We should look at all
> graph modules to see which are impacted.
