Fixes #38 : Got coverage analysis working in both phing and NetBeans.
Removed @covers annotations from test. They were causing errors and it is
better to start clean and add annotations as necessary to tweak output anyway.
Added properties and code to build.xml to initialize code coverage and a
test-report task to generate the report.
Added the reports directory to the clean task.
Adjusted the test task to not abort on test failure because of the current
phing issue with excluding groups.
Generated coverage report in NetBeans as well.
