The command returns the tabbingIdentifier +of the window prior to calling this function. If the optional newId argument +is omitted, the window's tabbingIdentifier is not changed. + +The purpose of the tabbingIdentifier is that NSWindows may only be grouped +together as tabs if they all have the same tabbingIdentifier.
