A serious bug in cluster

[yaox12]

A serious bug in cluster.py from line 193 to line 200 First, when assign points to the cluster they belong to, we should start from the points with higher local density. Second, you don't find the border region for each cluster, nor divide the points into cluster core and cluster halo according to the paper.

Thank you for the suggestion. As the code is a long time ago, so I'll read the paper again, and give the response asap.
