> Currently, aggregators and broadcast sets cannot be accessed through Gelly's  {{runVertexCentricIteration}} method. The functionality is already present in the {{VertexCentricIteration}} and we just need to expose it.
> This could be done like this: We create a method {{createVertexCentricIteration}}, which will return a {{VertexCentricIteration}} object and we change {{runVertexCentricIteration}} to accept this as a parameter (and return the graph after running this iteration).
> The user can configure the {{VertexCentricIteration}} by directly calling the public methods {{registerAggregator}}, {{setName}}, etc.
