    @vasia was completely right about the GGC algorithm, I misunderstood what it was supposed
to do. I implemented the correct version, but it turns out, after reading the GAS paper that
this algorithm has problems when executed synchronously (e.g., values can oscillate between
0 and 1). We had a discussion and decided to add a Connected Components example instead, as
well as a PageRank example, which I will implement shortly.
