Bryan Pendleton resolved DERBY-4363.
------------------------------------

       Resolution: Fixed
    Fix Version/s: 10.6.0.0

I fixed a small typo in wisconsin.java (the 'compress' argument was always being
set to 'false', ran a complete set of regression tests without problem, and submitted
this benchmark as revision 814237.

We may end up adding more types of GROUP BY statements to this benchmark
over time, but for now it seems like the work on this task is done.

> As part of ROLLUP implementation (DERBY-3002), it will be helpful to be able to measure the performance of GROUP BY.
> Using the o.a.dT.perf.clients framework, this sub-task proposes to add a GroupByClient to the performance runner
> library; the GroupByClient will run GROUP BY statements against the Wisconsin benchmark database.
