Extract and run code snippets in an automated fashion about rust-tuts

Thanks! I'll have a look at it, through snippets are embedded in Markdown and aren't all compilable as such with a main function etc. any idea?

I think the main code base just wraps the body of each example into a function and calls that function.

@huonw I decided to use handwritten tests units instead (for now at least), which has two advantages:

• it does not need crazy hack to have things working (and I'm noticeably thinking about input methods and BufferedReaders)
• it has guaranteed runnable code samples which I can link to (sometimes in the tutorial the code is not 100% runnable ie. lacks a main function or surrounding instructions whenever I want to show something specific).
