/**
 * Used to resolve resource URLs on `@Component` when used with JIT compilation.
 *
 * Example:
 * ```
 * @Component({
 *   selector: 'my-comp',
 *   templateUrl: 'my-comp.html', // This requires asynchronous resolution
 * })
 * class MyComponent{
 * }
 *
 * // Calling `renderComponent` will fail because `renderComponent` is a synchronous process
 * // and `MyComponent`'s `@Component.templateUrl` needs to be resolved asynchronously.
 *
 * // Calling `resolveComponentResources()` will resolve `@Component.templateUrl` into
 * // `@Component.template`, which allows `renderComponent` to proceed in a synchronous manner.
 *
 * // Use browser's `fetch()` function as the default resource resolution strategy.
 * resolveComponentResources(fetch).then(() => {
 *   // After resolution all URLs have been converted into `template` strings.
 *   renderComponent(MyComponent);
 * });
 *
 * ```
 *
 * NOTE: In AOT the resolution happens during compilation, and so there should be no need
 * to call this method outside JIT mode.
 *
 * @param resourceResolver a function which is responsible for returning a `Promise` to the
 * contents of the resolved URL. Browser's `fetch()` method is a good default implementation.
