karma + mocha tests

It's alive! 👍

I'm guessing you may not want this, but just in case: I converted your tests to use phantomJS (and Travis-CI), and easier browser testing. https://github.com/enketo/enketo-xpathjs/tree/master/test. I'd be happy to send a PR. I didn't update the benchmark page (and actually removed it in my fork).

(I still haven't found a bug.)

Heh, yes, I'm still kicking around :)
I did see the test conversion that you did in your fork, and I definitely like it. It would be a good thing to bring that into this repo as well.
