-----------------------------------------------------------------

The initial work has been completed.

Follow on tasks:

- support level
- remove the isSameEntity logic - which is only needed for the $it construct TEIID-4387
- create an rewrite optimization to turn a single expand into a left outer join, which will preserve the performance characteristics of the old logic

> To move TEIID-3039 we need to have xml document model style processing for expand support.  That is top down generation that supports arbitrary descendants - with targeted optimizations for projection minimization and dependent joins.
