Major design change -- see details.  This was a major challenge.

The design came about because I wanted to report results in 2 formats —
sorted by size and by method.  Previous design couldn’t do both.  This
was a big, big challenge.  Details below.

1. Completely re-designed TimingTests and TimingTest.
2. TimingTest now has all code for timing the method.
3. New class (helper) — IterationsTime.
4. TimingTest, IterationsTime, TimingTests — used in timing.
5. Instead of Format, we now have Report.
6. Report collects all timings and then prints them out.
7. New objects created to work with Report.
8. Report can data sorted by size or by method.
9. Related changes elsewhere.
10. Renamed or deleted objects.
