August 3 2014: Regex experimentation
	New Files:
		lexer_regex:
			This is most of the css2.1 specification in
			regex. I'm not sure that I want to work on the
			entire specification though. I'm probably going
			to just stick to handling a few sub sections of
			it. I'm probably going to be writing another css
			lexer later that is much simpler.
	Modified Files:
		.gitignore:
			I'm having it ignore documentation generated by
			doxygen for now. Maybe in the future I'll add
			it.
		readme:
			Added usability information. These are subject
			to change though.

		css_muncher:
			Added a few tests to look at the regex. These
			are going to be removed though.

Notes:
	Renamed the css test files.
