Provides a purely virtual base class for anybody that wants to receive notifications of
'activity' — any feedback from an emulated system which a user could perceive other than
through the machine's native audio and video outputs.
So: status LEDs, drive activity, etc. A receiver may choose to make appropriate noises
and/or to show or unshow status indicators.
