> TOTUPLE udf gets an input tuple, creates a new list, puts every field from
> the tuple into the list, and creates a new tuple by calling
> TupleFactory.newTuple(List<Object>) method -- which in turn allocates
> *another* list and copies everything in there.
> Simply returning the input tuple should be sufficient -- Pig already did the
> work of putting the arguments into a tuple.
