    This change configures your app to always load the most recent version of your app's JS bundle. On the first launch, this will correspond to the file that was compiled with the app. However, after an update has been pushed via CodePush, this will return the location of the most recently installed update.
 
    *NOTE: The `bundleURL` method assumes your app's JS bundle is named `main.jsbundle`. If you have configured your app to use a different file name, simply call the `bundleURLForResource:` method (which assumes you're using the `.jsbundle` extension) or `bundleURLForResource:withExtension:` method instead, in order to overwrite that default behavior*
