> 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}
