    Hi @vasia ,
    The PR was updated to include your suggestions. Last test fails for some reason, but that
shouldn't get in the way of reviewers :)
    As you can see, I went back to suqare one: I needed to test whether the exception is thrown.
I followed the degree approach. Hope it's fine!
    I would like to ask you to merge this before other vertex-centric PRs because of the following
    1). FCFS
    2). I had my share of merge conflicts for now :)
    3). I spoke to @markus-h the other day and he said there is no rush with #598 (which I
think is a good contribution, by the way)

> We would like to make the following extensions to the vertex-centric iterations of Gelly:
> - allow vertices to access their in/out degrees and the total number of vertices of the
graph, inside the iteration.
> - allow choosing the neighborhood type (in/out/all) over which to run the vertex-centric
iteration. Now, the model uses the updates of the in-neighbors to calculate state and send
messages to out-neighbors. We could add a parameter with value "in/out/all" to the {{VertexUpdateFunction}}
and {{MessagingFunction}}, that would indicate the type of neighborhood.
