Hey @andralungu,
I left some minor comments. Apart from those, I think we should also
address the previous comments on (a) returning an `Integer` instead of
`Tuple1`, (b) generic vertex keys and (c) allowing any vertex and edge value
type and replace them internally with `NullValue`.
I know that other library methods also have these problems (and there's a
JIRA), but this PR is open, so we can at least fix them for this one.
> Add a Vertex-centric Version of the Tringle Count Library Method

> Key: FLINK-2634
> URL: https://issues.apache.org/jira/browse/FLINK-2634
> Project: Flink
> Issue Type: Task
> Components: Gelly
> Affects Versions: 0.10
> Reporter: Andra Lungu
> Assignee: Andra Lungu
> Priority: Minor
>
> The vertex-centric version of this algorithm receives an undirected graph as
> input and outputs the total number of triangles formed by the graph's edges.
> The implementation consists of three phases:
> 1). Select neighbours with id greater than the current vertex id.
> 2). Propagate each received value to neighbours with higher id.
> 3). Compute the number of Triangles by verifying if the final vertex contains
> the sender's id in its list.
> As opposed to the GAS version, all these three steps will be performed via
> message passing.
