Clustering

A little bit complicated formula for clustering.
|X-m| > stdev
where X is the facebook value, m = max(center(cluster),mean(cluster)),
and stdev is standard deviation based of cluster based on m.
Then I merge clusters together that have size less than 5 to have less
low-sized clusters (works fine).

Modify the code according to your needs, for now, I just run the file
and print results.
