Greedy dbscan

WebDBSCAN is a greedy algorithm, so non-core points can be assigned to any cluster from which they can be reached. Thus, if a non-core point is reachable from multiple clusters, it can be assigned to any of those clusters. Such labellings must be ignored otherwise clusters could improperly merge when combining the cluster IDs.
