Runtime parsing

[ebryn]

Prius should be usable purely at runtime via a <script> include and special <link> tags that will handle the loading/parsing of CSS

TODOs:

• [x] Convert our dependencies to ES6 so we can include the parser at runtime
• [x] Refactor tests to utilize runtime rather than Babel transforms

:+100: The elephant in the room is that using AJAX means you might have to deal with CORS. Is that a viable go-to-market strategy?

Since less.js basically does the same thing I think that is fine. There is no mechanism AFAIK for reading the source of an external stylesheet that has been loaded from another domain.

This approach is one I want to support but I expect most people will use the hybrid build/runtime setup.

Oh sweet. Nice find re: less.js

Completing these tasks will also unblock #10
