Details of the feature

The notebooks spawned from this package share the MATLAB workspace from the singular MATLAB process backing these notebooks.

Make it possible for notebooks to have their own MATLAB processes thereby avoiding the MATLAB workspace overlap between notebooks running on the same Jupyter server.
