Update MATLAB case in pom.xml

MATLAB should be all uppercase.
Add MatlabControl dependency

The MATLAB scripting will use the MatlabControl library for access into
MATLAB (see https://code.google.com/p/matlabcontrol/).
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.
