- Added unique failure tokens to iw::core() -- this allows for functions to return a unique string which can be checked immediately to determine if a unique failure occurred.  This differs from exceptions in that the function can run "normally" and fail gracefully if need be, but it can also return values like NULL, FALSE, etc, if it may do so legitimately.
