August 4 2014: Working Lexer
	New Files:
		cssLexer:
			The css lexer is a subclass of the base lexer
			which can read and analyse css code.

			The css lexer reads numbers, identities, colons,
			semicolons, brackets, braces, and parethesis,
			commas, comments, newlines, whitespaces, urls,
			strings, and bad strings.
			Some other components are there, but not
			implemented. Also, there could be some clean up
			of the different tag names.

	Modified Files:
		css_muncher.py:
			Made to use the working css lexer.
		lexer.py:
			Removed unecessary commented out code.
		single.vss:
			Edited to test parts of the css lexer.
