WIP: replace with pom-scijava update
Create MIJPrefService

Adds an alternate PrefService implementation to avoid using the
java.util.prefs-based default implementation.

This new service will only be disabled when running MIJ. Outside of MIJ
it should behave as the DefaultPrefService does.

This is necessary to avoid a bug in MATLAB with this package. See:

Convert Datasets to MatlabNumericArrays

Created a Converter plugin that knows how to convert Datasets to
MatlabNumericArrays. These can then be passed to MATLAB as matrices via
MatlabControl API.
Automatically convert Datasets to NumericArrays

Created an input preprocessor that will use the active dataset to
populate MatlabNumericArray @Parameters. Note that @matrix is aliased to
MatlabNumericArray.
Create Miji tests

Added tests for basic MIJ functionality, including conversion of
datasets to matrices in MATLAB and summing or multiplying them.
Streamline tests

Extracted common code and cleaned up the test code in general.
Manual code clean up

Added documentation, fixed warnings, etc.. for MATLABDatasetCovnerter
and NumericArrayPreprocessor.
Apply code cleanup

Used Eclipse's style template to clean up code.
