/** A class that can return a Stateful object which is the subject of a MementoCommand.

* The existence of this class means that the undo record can refer to objects which

* when MIDI automation is edited, undo records are written for the AutomationList being
* changed. However this AutomationList is a temporary structure, built by a MidiModel,
* which doesn't get written to the session file. Hence we need to be able to go from
* a MidiSource and Parameter to an AutomationList. This Binder mechanism allows this
