> Create a new UDF that is similar to "FirstTupleFromBag" but this one will be more general,
and not only the first tuple.
> This new UDF can be called "TupleFromBag" and will get three parameters:
> 1. DataBag
> 2. Index
> 3. Optional Default Tuple
> There should be a consideration to refactor FirstTupleFromBag to call TupleFromBag, for
reusability consideration.
