Rewritten in CoffeeScript

- The code has been completely rewritten in CoffeeScript. More readable,
mantaining the code is easier, much faster to code. I HAVEN'T TESTED THE
CODE YET, BUT IT MUST WORK!
- New documentation generator is Codo
(https://github.com/coffeedoc/codo). It is CS-specific.
- I will import the documentation from the old source files ASAP.
