The default task won't work... that is a single-run process, so it prevents you from accessing http://localhost:9876/ in the browser to run the Karma tests. If you change the task to 'karma' that will allow you to visit the URL and run the tests, but you have to change at least 1 file first. I assume there is a way to have ```grunt dev``` both run the 'karma' task on startup and when any of those watched files have changed, but I haven't tried to. If you're able to figure it out when you update this pull request, go for it
