Ariticle: Spriting with Sass and Compass

@goschevski  this is the edited version of your original article. I ended up making a number of changes to keep things simple and make it easier to read. It has a new intro and a number of illustrations. Have a look and let me know if you want to make any additional changes.

I still need a bio from you. :)
