 // TabViewPickerTable is an NSOutlineView that can be used to switch between the
 // NSTabViewItems of an NSTabView. To use this, just create a
 // TabViewPickerTable in Interface Builder and connect the |tabView_| outlet
 // to an NSTabView. Now the table is automatically populated with the tab labels
 // of the tab view, clicking the table updates the tab view, and switching
 // tab view items updates the selection of the table.
