> The cartesianProduct function emits multiple tuples from a single tuple. To
> save the cartesian product in another collection it would be useful to be
> able to dynamically assign new unique id's to tuples. The uuid() stream
> evaluator will allow us to do this.
> sample syntax:
> {code}
> cartesianProduct(expr, fielda, uuid() as id)
> {code}
