5346e95dda NGQP working with virtualt tables, though many legacy tests fail and there 
are yet some memory leaks.

a184fb87b8 More bug fixes to the WhereLoop generator and the solver in NGQP. 
Now finds the best plan for TPC-H Q8.  This seems to prove the
concept, but there is still much work to be done.
