// C++ controller for the bookmark menu; one per AppController (which
// means there is only one). When bookmarks are changed, this class
// takes care of updating Cocoa bookmark menus. This is not named
// BookmarkMenuController to help avoid confusion between languages.
// This class needs to be C++, not ObjC, since it derives from
// BookmarkModelObserver.
//
// Most Chromium Cocoa menu items are static from a nib (e.g. New
// Tab), but may be enabled/disabled under certain circumstances
// (e.g. Cut and Paste). In addition, most Cocoa menu items have
// firstResponder: as a target. Unusually, bookmark menu items are
// created dynamically. They also have a target of
// BookmarkMenuCocoaController instead of firstResponder.
// See BookmarkMenuBridge::AddNodeToMenu()).
