Description

The motivation for this enhancement came from both Kepler (wanting to merge data from like-structured datatables in an EMLDataSource actor) and from the FIRST project where a similar function is desired (but across many different packages).
Implementation is intended to be a straightforward SQL union/union all between two or more Query objects.
