Possibly include correct answers in an alternate branch?

[0x647262]

I've completed the koans, but I have little idea of knowing if what I did was actually "correct". I bring this up because there are some problems I probably mis-interperated, and left me a little confused. (Even after using shellcheck to double-check the user's portion of the assertEqual checks, I still don't know if my answers are "correct")

If you'd be interested in adding an answers branch, I'd be willing help!
