Class to output CSS data quickly for public facing pages.

This class is not designed to be used with the MVC structure; this allows us to significantly reduce the amount of overhead in a request.

This class is entirely self sufficient. It handles parsing the input, getting the data, rendering it, and manipulating HTTP headers.
