Yes, unless anyone testing can find issues with this patch (or with the one Grant posted earlier,
as mine contains his), it is meant to be committed.

>>> 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.
