Description

Currently in the graph package, the iteration continues till the nodes are no longer updated (absolutely) or the maximum number of iterations has reached.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.
