JS/CSS Minifier Benchmarker

To use:

1. Add files you want tested to the approperiate folder (js_files or css_files).
2. Add minifiers you want to the compilers.py

Currently, we use a few minifiers already:

• YUICompressor: Already comes packaged
• UglifyJS: use npm install -g uglify-js
• Clean CSS: use npm install -g clean-css
• LESS CSS: use npm install -g less
