#pragma mark ABSTRACT
// This subclass of NSViewController is responsible for the splitview and the outline view which shows the library
// nodes (upper half of the window). It loads the views and is also responsible for handling selection and expansion
// of nodes, and for making sure that the state is persistent across application launches.
// Please note that this controller is the delegate of all views, so do not modify those delegates. If you do need
// delegate messages for various events, then use the delegate methods of IMBLibraryController...
// There is an instance of this controller per window and per media type. If we have 4 media types (photos, music,
// video, links) and 3 windows containing media browser UI, then we need 12 instances of this controller. This
// controller coordinates between the views and the IMBLibraryController. Essentially IMBLibraryController is a
// backend controller, while IMBNodeViewController is a frontend controller.
