Description

The current code organization is a little inconsistent. We had a dedicated package for query optimization but no package for SQL support, which is just one API and we will soon have a new Table/DataFrame API which is an alternative, but will leverage the same logical plan and query optimizer, so I plan on moving things around a little.
