Added a simple C-based test framework and an example program that uses it to run through some simple unit tests. This is new code inspired primarily by the approaches of Google Test, Boost Test, JUnit and TestNG. Factors of others were also considered during design and implementation. Signed-off-by: Jon A. Cruz <jonc@osg.samsung.com> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.co.uk>
