> The Gather-Sum-Apply-Scatter 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.
> Gather: no-op
> Sum: create a set out of these neighbours
> Apply: attach the computed values to the vertices
> 2). Propagate each received value to neighbours with higher id (again using GSA)
> 3). Compute the number of Triangles by verifying if the final vertex contains the sender's
id in its list.
