> The gelly-examples has grown quite big (14 examples) and contains several examples that illustrate the same functionality. Examples should help users understand how to use the API and ideally show how to use 1-2 features.
> Also, it is helpful to state the purpose of each example in the comments.
> We should keep the example set small and move everything that does not fit there to the library.
> I propose to remove the following:
> - ClusteringCoefficient: the functionality already exists as a library method.
> - HITS: the functionality already exists as a library method.
> - JaccardIndex: the functionality already exists as a library method.
> - SingleSourceShortestPaths: the example shows how to use scatter-gather iterations. HITSAlgorithm shows the same feature plus the use of aggregators. I propose we keep this one instead.
> - TriangleListing: the functionality already exists as a library method
