* Relicenced to BSD / Apache2.0 with full agreement of contributors.
* Substantially improved documentation in README. (mbp)
* Rename TestResource to TestResourceManager leaving TestResource as an alias.
Fixes bug #520769.
* Test sorting no longer performs N! work on tests that can never benefit from
order optimisations (when resources are not shared an arbitrary order is
sufficient). Partial fix for bug #522338.
* Test sorting now uses a heuristic on each partition to get a sort that is
no worse than twice the optimal number of setup/teardown operations and is
fast to calculate. Fixes bug #522338
