/**
This handles the plugin duties, and the midi encoding and decoding,
and the signal callbacks, mostly from ARDOUR::Route.
The model of the control surface is handled by classes in controls.h
What happens is that each strip on the control surface has
a corresponding route in ControlProtocol::route_table. When
an incoming midi message is signaled, the correct route
is looked up, and the relevant changes made to it.
For each route currently in route_table, there's a RouteSignal object
which encapsulates the signals that indicate that there are changes
to be sent to the surface. The signals are handled by this class.
Calls to signal handlers pass a Route object which is used to look
up the relevant Strip in Surface. Then the state is retrieved from
the Route and encoded as the correct midi message.
