Re-named packages. Fixed 1 bug in last release.

1. Renamed packages:
   (a) output —>  reporting;
   (b) rows —>  layouts;
   (c) views —> rendering;

2. TableBuilder moved to timer.reporting.base package.

3. Fixed 1 bug in last release:
 — TimingTests copy() NOT passed to report.run();
 — Now fixed.  TimingTests copy() passed to report.run().

4. Made TimingTests.nothing() final — a minor change.
