-------------------------------------------------------------
Tests added and passing.
This does not add any additional evaluators. I think those can be added in
other tickets. All evaluators are supported by this stream so anything you
think to add (regex matching, sentence creation, etc...) will work. The stream
works with both multi-valued and single-valued fields in so much that it will
treat single-valued fields as a collection with a single item.

> Currently all the Streaming Expression such as rollups, intersections, fetch
> etc, work on single value fields. The *cartesian* expression would create a
> stream of tuples from a single tuple with a multi-value field. This would
> allow multi-valued fields to be operated on by the wider library of Streaming
> Expression.
> For example a single tuple with a multi-valued field:
> id: 1
> author: [Jim, Jack, Steve]
> Would be transformed in the following three tuples:
> id:1
> author:Jim
> id:1
> author:Jack
> id:1
> author:Steve
