And also added webpack-bundle-analyzer so we can see what is included in production bundles

You can run it using yarn analyze or npm run analyze it will show something like this

You can know why easily by running yarn why create-react-class and it tells you

For some reason I am getting an error saying that r is not a function on app.js line 7 when I try to run this in production mode on a server. Any idea what I could be doing wrong?
