I can't figure out how to properly do the the Var->sublevels_up search in the
existing code, partly because I can't figure out what it is doing.

It will take me a few days more to do it. I just can't look at the code
anymore.

OK, I think I have a handle on it now. Should be two days.

^^^^^^^^^^^^^^^^
It says what range table should be used to find Var' relation.

My problem was the ParseFunc really does much more than handle
functions. It handles:

colname
rel.colname
rel.colname.func
sum(colname)
sum(rel.colname)

and probably much more than that.
