A CSS validator for the command line, with a bit of linting built in.

In progress, and intended only as a mechanism to teach myself C: if you need to validate/minify CSS, I'd suggest using something like YUI Compressor or Norm's CSS Prepare.

• Base structure (StatefulString, Token, and Tokenizer "objects").
• Unit test framework (Check)
• Tokenization, consistent with the rules laid out in the spec.

• Decide on an error handling mechanism.
• Turn the token stream into a parse tree.
• Validate the tree.
• Implementing some linting tests (vendor-prefixes, for example)
• Integrate some of Norm's tests (maybe?)
