Test examples

@dustingetz:  Here are two test examples, with one running through the browser and the other through a PhantomJS, both via Mocha.

1.  In one console tab, start `grunt test`.  In another tab, start a server in the root of the project via `httpster` or whatever (so `node_modules` can be referenced), then navigate into `test/html` you should see the full mocha spec running.  For complex debugging (including logs) I would stay in here.

2.  When you run `grunt test` it will automatically spin up a PhantomJS instance and, via grunt watch, continually watch your test directory for changes, recompile, and then rerun the spec.  I added examples of both passing and failing tests:
