Only browser shims

If you only want to bring in the browser shims and not the JS language shims (from airbnb-js-shims), you can import airbnb-browser-shims/browser-only. If you choose this route, you will want to be sure that you are properly bringing in the language shims for the browsers you support somehow. For example:

import 'airbnb-js-shims/target/es2015';
import 'airbnb-browser-shims/browser-only';
