Some code for clustering, but coefficient is not correct, and takes too long to calculate anyway
Basic control flow is in place. Functions implemented to getNextNode based on relationship strength, apply and remove labels, and initialise cluster (which adds first two nodes to cluster, as coefficient cannot be calculated for clusters of size less than 3)
Clusters now being calculated. Now need to be returned to the client.
Server now calculates cluster, and returns to client
Clusters now added to graph.
