Added some string processing tests

Sorry for not getting to this sooner -- I'd like to pull this in, but I'd love it if you can update it to use camelCase for the variable names, per the style of the rest of the repo.

Thanks for getting back to me, sorry it took me a while, i was out of town. Hopefully I fixed everything, but let me know if I missed something.

Thanks! One other thing, looks like there's not an app/strings.js file in this pull request? If you can add one and stub out the functions (like you see in other app/*.js files) that would be great and I'll get this in. Thanks for adding these!

[pete-the-pete]

I added in the stubs, let me know if there's anything else you need me to do.

The variable mid is going to end up just being the string's length, so it doesn't seem right to expect these two things to be equal.

@pete-the-pete, thanks so much for this PR! Sorry that it's taken a bit for it to get merged in, but I'm going to make these last few changes over in #102 before I merge it in. I'm going to close this PR in the meantime. Oh, and, don't worry – you'll still be the name on the commit that lands in master.

Thanks again :)
