test suite, unit tests
The basic test suite should test parsing using local copies of the DCC (XML) documents.
We might also want to add some tests that can be manually activated that actually communicate with the DCC to test the HTTP interfaces. Might be too much to launch a mini DCC server at this point. We want to be able to turn this test on and off, since it will require LIGO.ORG credentials and network access, which we don't want to assume for all builds.
