New port: devel/py-cluster

Python-cluster is a simple package that allows to create several
groups (clusters) of objects from a list. It's meant to be flexible
and able to cluster any object. To ensure this kind of flexibility,
you need not only to supply the list of objects, but also a function
that calculates the similarity between two of those objects.
For simple datatypes, like integers, this can be as simple as a
subtraction, but more complex calculations are possible.
