> Currently in the graph package, the iteration continues till the nodes are no
> longer updated (absolutely) or the maximum number of iterations has reached.
> It doesn't support testing the node changes with some tolerance and then stop
> the iterations as in the case of page rank.
> The above scenario might be applicable besides page rank also.
