The matlab actor always stops the matlab process when model execution ends. It
would be nice if the actor could (optionally) keep it running. This
functionality would be useful, for example, to continue displaying matlab plots
after the model completes, or reuse the matlab process for subsequent model
executions.

The difficulty in implementing this is knowing when to stop the matlab process.
It should be done before the JVM exits. I don't think finalize() is a solution
since it is not always called.
