Aggregators in GraphX

Hi,

Does GraphX currently support Giraph/Pregel's "aggregator" feature? I 
was thinking to implement a PageRank version that is able to correctly 
handle dangling vertices (i.e. vertices with no outlinks). Therefore I 
would have to globally sum up the rank associated to them in every 
iteration, for which I need the aggregator feature. Could Spark's 
accumulators be used for that?

Best,
Sebastian
