 #pragma mark - NSSplitViewDelegate
 
 /* Return YES if the subview should be collapsed because the user has double-clicked on an adjacent divider. If a split view has a delegate, and the delegate responds to this message, it will be sent once for the subview before a divider when the user double-clicks on that divider, and again for the subview after the divider, but only if the delegate returned YES when sent -splitView:canCollapseSubview: for the subview in question. When the delegate indicates that both subviews should be collapsed NSSplitView's behavior is undefined.
