/**
 * This method creates a list of URLs to precache, referred to as a "precache
 * manifest", based on the options you provide.
 *
 * The manifest is injected into the `swSrc` file, and the placeholder string
 * `injectionPoint` determines where in the file the manifest should go.
 *
 * The final service worker file, with the manifest injected, is written to
 * disk at `swDest`.
 *
 * This method will not compile or bundle your `swSrc` file; it just handles
 * injecting the manifest.
 *
 * ```

 * // for the full set of options and defaults.
