 * Creates a new instance of a [[lastItem]] node, which is a type of collection transform used when taking
 * the last item out of a collection.
 * It also comes with a shorthand version to be used in the [ref](_utils_ref_.html#ref). See the **References to
 * items in collections** example from the [ref](_utils_ref_.html#ref) documentation.
 *
 *
 * @example **Take last item (using transform)**
 * ```js
 * import muster, { entries, query, ref, lastItem, withTransforms } from '@dws/muster';
 *
 * const app = muster({
 *   numbers: [1, 2, 3, 4, 5],
 * });
 *
 * const item = await app.resolve(query(ref('numbers'), withTransforms([
 *   lastItem(),
 * ], entries())));
 * // item === [5]
 * ```
 * This example shows how to use the [[lastItem]] transform to take the last item out of a
 * collection.
