* This copies over a set of runtime libraries used by Workbox into a

*
* As an alternative to deploying these local copies, you could instead use
* Workbox from its official CDN URL.
*
* This method is exposed for the benefit of developers using
* [injectManifest()]{@link module:workbox-build.injectManifest} who would
* prefer not to use the CDN copies of Workbox. Developers using
* [generateSW()]{@link module:workbox-build.generateSW} don't need to
* explicitly call this method, as it's called automatically when
* `importWorkboxFrom` is set to `local`.
*
* @param {string} destDirectory The path to the parent directory under which
* the new directory of libraries will be created.
* @return {Promise<string>} The name of the newly created directory.
