/**
 * Creates a new instance of a [[format]] node, which is used converting a values of objects to string and inserts them into
 * another string. It uses the same syntax as the [Format Literals](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals)
 * from JavaScript.
 *
 *
 * @example **Simple format string**
 * ```js
 * import muster, { ref, format } from '@dws/muster';
 *
 * const app = muster({
 *   name: 'Bob',
 * });
 *
 * const greeting = await app.resolve(format('Hello, ${name}', {
 *   name: ref('name'),
 * }));
 * // === 'Hello, Bob'
 * ```
 * This example shows how to use the [[format]] to create a string from a given format
 * and a value of a graph node.
