---------------------------------------------------------------
Running DisplaySpectralKMeans gives this error:
FileNotFound:Exception
examples/output/calculations/laplacian-48/tmp/data not found
In fact, the data is stored here:
examples/output/calculations/laplacian-48/tmp/1314835934416372000/DistributedMatrix.times.inputVector/
Also, the directory with "diagonal" does not have a number; it assumes it is
underneath a job-unique path:
{code}
examples/output/calculations:
diagonal laplacian-48 seqfile-160
{code}
(The jobs create unique directories with a random 8-bit number.)
Any hints on exactly which API call is wrong?

> 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.
