> The vertex-centric SSSP example and library method send unnecessary messages
> during the first superstep

> The result is correct, but the current implementation has unnecessary message
> overhead in the first superstep. The Messaging function should only produce
> messages from the source during the first superstep. This can be fixed with a
> simple check of the vertex value.
