Affinity Prop  clustering. New results in Output

Much cleaner clusters emerging without having to specify a cutoff. The
number of clusters have gone up..and i guess thats the reason for the
clean clusters.
Two functions added to the new AffinityPropogationClustering.py , the
internal doesnt work yet , but the external one does.
Added 2 o\p formats CDT, GCT to help comparison.
