title: delegate member in NSMenu
body: <p>From  my understanding  the  delegating  class is the  one  which  always inherits from <code>NSResponder</code> class and <code>delegate</code> is only available  to  classes that  inherits from  <code>NSResponder</code>. <code>NSMenu</code> inherits directly from <code>NSObject</code>, so then why do i see <code>deletgate</code> in the  <code>outlets</code>?
  Or is it that  i  misunderstood the options that you see after  ctrl-click on an object in Interface Builder?  I see <code>Outlets</code>,  <code>Referencing outlets</code>, <code>Received Actions</code> , what does these mean then?
  I am  using Xcode 4  (10.7.3), if that matters.</p>
