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

[~jamestaylor]The temp schema is to work with Aggregate projection to replace rowProjector.
All UnionAllIT tests passed with Plan compiled Order By and Limit. 

Wrapping another Select over current Union All selects we need to specify a table. A dummy
table or Null table did not work since parser needs a real table to resolve column information
etc. I have to say if we have taken my very early approach of passing down rowProjector, we
can simplify the approach quite bit.
