Add a way to test xref parsers, and a first test, for WormbaseDirectParser.
I will work on WormbaseDirectParser soon, aiming to develop a more correct way to handle UniProt xrefs for c. elegans. I'll add some tests to the code I touch, probably.
Developers of xref parsers could add their tests to this module and get benefits like I expect - see the section, "Benefits"
Other people can edit WormbaseDirectParser and see if it still works. The test documents a possible bug in WormbaseDirectParser (some duplicate direct_xrefs).
The repo will take slightly longer to download, and the test suite will run longer.
The test runs fine with
prove, although a module issuing mysql commands through the shell is warning me about how using password on the command line can be insecure. I think the Travis setup will be fine with how I changed it.
