/* HIGH-LEVEL NOTES:
- The QCPlugInViewController class provides a controller object used to present a user interface to edit internal settings of QCPlugIns.
- The user interface is represented by a view containing controls which communicate with the plug-in instance through Cocoa bindings to edit its internal settings.
- In its typical usage, the plug-in view controller will handle all the user interface by loading the nib file and being the target of the Cocoa bindings for the controls.
- The internal settings of the plug-in must be accessed through Key Value Coding (KVC), and all the KVC keys representing the internal settings of the plug-in should be listed in its +plugInKeys method.
- The plug-in view controller expects the nib file to have its "File's Owner" of class "QCPlugInViewController", and have its "view" outlet connected to the view containing the editing controls.
- The controls are bound to the "File's Owner" as the target and "plugIn.XXX" as the model key path, where XXX is the KVC key for a given internal setting of the plug-in instance.
- Do not call -setRepresentedObject: or -setView: after initializing the QCPlugInViewController as this is unsupported.
