+// TabViewPickerTable is an NSTableView 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.
