Jeff Eastman updated MAHOUT-30:
-------------------------------

    Attachment: MAHOUT-30b.patch

This patch is a complete implementation of a non-M/R Dirichlet Process clustering algorithm.
It has been refactored significantly from the above. I will describe these changes in a subsequent
posting. I'd like to commit this to trunk in time for 0.1 if people agree.
