Why only offering this method for Gelly? Can't we generalize the index
algorithm for generic types? It could also be useful for the ML library, for
example. I'm thinking of something like `zipWithIndex` what is also offered by
Spark's API.
> Add a library method that assigns unique Long values to vertices

> Key: FLINK-2150
> URL: https://issues.apache.org/jira/browse/FLINK-2150
> Project: Flink
> Issue Type: New Feature
> Components: Gelly
> Reporter: Vasia Kalavri
> Assignee: Andra Lungu
> Priority: Minor
> Labels: starter
>
> In some graph algorithms, it is required to initialize the vertex values with
> unique values (e.g. label propagation).
> This issue proposes adding a Gelly library method that receives an input
> graph and initializes its vertex values with unique Long values.
> This method can then also be used to improve the MusicProfiles example.
