 Abstract: The main demo application controller. This class is the delegate for the main NSApp instance. This class manages the windows that are open, and allows the user to create a new one with the 'Available Sample Windows' table view. Bindings are used in the 'Available Sample Windows' table for the content. The TableView is bound to the _tableContents, which is an array of NSDictionary objects that contain the information to disply.
