Released 0.1

[killercup]

Hey folks, just a quick note that I've wrapped the tremendous work you've been doing into a release!

Referring back to #10, we have:

• Made this a library
• Added support for names that are not valid Rust identifiers
• Switched to bitvec
• Added a whole new testing framework
• Implemented arbitrary and fixed a bunch of other stuff

Thanks again @marcelbuesing and @andresv!
