Added some tests for Node

[adam-lynch]

These will fail right now but pass once #58 is merged.

[adam-lynch]

Don't merge yet. Gotta get npm test to reach into node_modules & call Grunt, instead of requiring grunt-cli to be installed.

[adam-lynch]

Ok, this is ready for merging (still will fail unless #58 is merged though).

Note: now grunt-cli needs to be installed globally to run the tests. There's no way to reach into node_modules like I said (which will work on all platforms). The Travis build will now install grunt-cli before running the tests.

I think the tests are still failing:

Done. Your build exited with 1.

[adam-lynch]

That's because you merged the fix but I haven't pull that change down onto my fork's branch. Will do there in a minute.

[adam-lynch]

Tada ^

[hassankhan]

I would've thought the pull request branch on Travis-CI would run against master on the repo, not your fork. Oh well, thanks for sorting that out 👍

[adam-lynch]

Maybe it would if there wasn't merge conflict
