/* 

TO DO

1) Reduce CSS duplication
   - Ideally just a single build - global.scss turns into /build/global.css
   - Can Autoprefixer output minified?
   - If it can, is it as good as cssmin?
   - Could Sass be used again to minify instead?
   - If it can, is it as good as cssmin?

2) Better JS dependency management
   - Require js?
   - Can it be like the Asset Pipeline where you just do //= require "whatever.js"

3) Is HTML minification worth it?

4) Set up a Jasmine test just to try it.

5) Can this Gruntfile.js be abstracted into smaller parts?
