title: NSTableViewDelegate with 2 tables and tableViewSelectionDidChange:(NSNotification *)aNotification
body: <p>I have 2 tables whose delegate is the same object. Struggling with the syntax on how to accommodate this.  I have the other delegate methods working correctly as they are passing the NSTableView object. </p>
  
  <p>An example most appreciated</p>
  
  <pre><code>- (void)tableViewSelectionDidChange:(NSNotification *)aNotification {
  
  }
  </code></pre>
