/**

* This method can be called multiple times.
*
* Please note: This method **will not** serve any of the cached files for you.
* It only precaches files. To respond to a network request you call
* [addRoute()]{@link module:workbox-precaching.addRoute}.
*
* If you have a single array of files to precache, you can just call
* [precacheAndRoute()]{@link module:workbox-precaching.precacheAndRoute}.
