Thanks for the reality check, @frrrances. As we chatted about before - this file is the vendor's original code that my static build assistance app, CodeKit, is then minifying/compressing for the .min.js version that's called in the index.html view. 

I don't think it hurts to keep this here as anyone can update it and if they're using CodeKit to watch their local directory, the minified version will be produced automatically upon update. It also informs future devs of the version the site/page is using currently.
