     * {@link IterableDiffers} instance.

     * The following example shows how to extend an existing list of factories,
           * which will only be applied to the injector for this component and its children.
           * This step is all that's required to make a new {@link IterableDiffer} available.
     *
     * ### Example
     *
     * ```
     * @Component({
     *   viewProviders: [
     *     IterableDiffers.extend([new ImmutableListDiffer()])
     *   ]
     * })
     * ```
