/**
 * Creates an instance of an [[remoteItemAt]] node, which is a type of a graph node used when inserting an item into
 * a mutable collection at a specific index.
 *
 *
 * @example **Remove a number from a mutable collection**
 * ```js
 * import muster, { arrayList, entries, query, ref, removeItemAt } from '@dws/muster';
 *
 * const app = muster({
 *   numbers: arrayList([1, 2, 3]),
 * });
 *
 * app.resolve(query(ref('numbers'), entries())).subscribe((value) => {
 *   console.log(value);
 * });
 *
 * await app.resolve(removeItemAt(ref('numbers'), 1));
 *
 * // Console output:
 * // [1, 2, 3]
 * // [1, 3]
 * ```
 * This example shows how to remove item at a specific index from a mutable collection.
 *
 *
 * @example **Remove a branch from a mutable collection**
 * ```js
 * import muster, { arrayList, entries, key, query, ref, removeItemAt, toNode } from '@dws/muster';
 *
 * const app = muster({
 *   people: arrayList([
 *     { firstName: 'Lizzie', lastName: 'Ramirez' },
 *     { firstName: 'Charlotte', lastName: 'Schneider' },
 *   ]),
 * });
 *
 * app.resolve(query(ref('people'), entries({
 *   firstName: key('firstName'),
 * }))).subscribe((value) => {
 *   console.log(value);
 * });
 *
 * await app.resolve(
 *   removeItemAt(ref('people'), 1),
 * );
 *
 * // Console output:
 * // [{ firstName: 'Lizzie' }, { firstName: 'Charlotte' }]
 * // [{ firstName: 'Lizzie' }]
 * ```
 * This example shows how to remove a branch at a specific index from a mutable collection.
