Excluding peerDependencies

On library development, one might want to set some peer dependencies, and thus remove those from the final bundle. You can see in Rollup docs how to do that.

Good news: the setup is here for you, you must only include the dependency name in external property within rollup.config.js. For example, if you want to exclude lodash, just write there external: ['lodash'].

This project refer to barhandles.
