Of course, the results don't really speak well of SKM, but at least there are some results!

> I've committed a new display example that attempts to push the standard mixture of models
data set through spectral k-means. After some tweaking of configuration arguments and a bug
fix in EigenCleanupJob it runs spectral k-means to completion. The display example is expecting
2-d clustered points and the example is producing 5-d points. Additional I/O work is needed
before this will play with the rest of the clustering algorithms.
