It was a bit of an odyssey but I was able to push down the HAVING clause. I pushed the commits

>    The Presto SQL Parser was perfect for phase one of the SQLHandler. It was nicely split
off from the larger Presto project and it did everything that was needed for the initial implementation.
> Phase two of the SQL work though will require an optimizer. Here is where Apache Calcite
comes into play. It has a battle tested cost based optimizer and has been integrated into
Apache Drill and Hive.
> This work can begin in trunk following the 6.0 release. The final query plans will continue
to be translated to Streaming API objects (TupleStreams), so continued work on the JDBC driver
should plug in nicely with the Calcite work.
