> Currently Graph API is such that when a vertex doesn't receive any messages, compute() is not called upon it.
> One way to change it is let the user decide when the algorithm has to stop.
> For this we need to add a voteToHalt() function with each vertex.
> And maintain a state variable with each vertex. A vertex which has votedToHalt() doesn't send messages in the next superstep. However if it receives any message, its voteToHalt() ends and it is again eligible to send messages.
> When all vertices have votedToHalt() algorithm should end.
