Fixes to multi sub and multi pub.

Removes receiving and sendingTest for now as rospy integration and how_to cover
similar issues (though they could be made more robust).

Now that registerPublisher() and registerSubscriber() are public, mode has been
removed and these functions should be called directly (or just call publish() or
subscribe()).
