/**
 * This module executes inside of electron's main process. You can start
 * electron renderer process from here and communicate with the other processes

 *
 * When running `yarn build` or `yarn build-main`, this file is compiled to
 * `./app/main.prod.js` using webpack. This gives us some performance wins.
