/**
* Abstract base class for a panel instrument.
*
* A panel instrument consists of zero or more actions, associated
* with mouse clicks in rectangular areas. Currently, the only
* concrete class derived from this is FGLayeredInstrument, but others
* may show up in the future (some complex instruments could be
* entirely hand-coded, for example).
