Jon A. Cruz 5a75a41d07 Added simple unit/integration test framework and corresponding test program.
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.
