Add MATLAB scripting classes

First cut at implementing the scripting classes to facilitate MATLAB as
a scripting language in in the SciJava framework.
Create unit tests

Added a MATLABTest class to verify basic scripting functionality.

More advanced tests are required to be run from MATLAB itself, and are
thus more appropriate in other components.
