/**
 * 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 regular expression
 * `injectionPointRegexp` determines where in the file the manifest should go.
 *
 * The final service worker file, with the manifest injected, is written to
 * disk at `swDest`.
 *
 * @param {Object} config Please refer to the
 * [configuration guide](https://developers.google.com/web/tools/workbox/modules/workbox-build#full_injectmanifest_config).
 * @return {Promise<{count: number, size: number, warnings: Array<string>}>}
 * A promise that resolves once the service worker file has been written to
 * `swDest`. The `size` property contains the aggregate size of all the
 * precached entries, in bytes, and the `count` property contains the total
 * number of precached entries. Any non-fatal warning messages will be returned
 * via `warnings`.
