     File: MyDocument.h

 Abstract: A subclass of NSPersistentDocument that illustrates how to use a directory wrapper to allow the document to be saved as a package.

 In addition to the usual Core Data store, the document manages a file that contains the data for a picture.

 The user interface is configured using Cocoa bindings.  An array controller manages the display of a collection of Item objects, and the data for the NSImageView is managed using a binding to the document's 'picture' property.
