  Create a basic test suite for the library and test oid functions This is a horribly simple test suite that makes it fairly easy to put together some basic function level unit tests on the library. Its patterned somewhat after the test suite in git.git, but also after the "Check" test library. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
