Matlab client via Matlab Engine?

[imalsogreg]

Consider using Matlab Engine to run matlab functions from python.

This would force the user to get python <-> Matlab working on their own (usually a half-hour struggle); save us from writing a very non-DRY matlab client (with all the serialization/deserialization of cbaas datatypes)

But Python's view of an image is a numpy.array. Is this the right representation for an image in matlab, too?
