Review Comment:
I have mixed feelings about this.
I don't particularly like making UnparseTranslator dependent on some of
these other classes. I suppose RexNode and ASTNode do not matter too much since
they will always be dependencies but i'm not thrilled about adding a dependency
to RowResolver.
Having said that, they are in the same package right now and it will be easy
enough to separate them, so I don't mind doing what you propose.
