Code coverage information is now gathered via phpdbg (a separate executable) by if available rather than xdebug, as the latter is hard to turn on and off.
A "test:quick" task has also been added to Robo, which excludes 31 tests which together account for almost two thirds of the test run time. This should pave the way for testing to be added as a commit hook for Git.
Includes PHPDoc license tag in the file-level block with accompanying copyright notice.
Also added an AUTHORS file on the off chance of outside contributions
