/**
 * Creates a new instance of a [[createSetter]] node, which is a type of a [[NodeDefinition]] used inside
 * the [[query]] when requesting Muster to return a function that can be used to imperatively set a Muster variable.
 * This node is extensively used by Muster React to create setter functions.
 * It is intended to be used by any other libraries integrating Muster.
 * The setter function automatically un-wraps a returned value with the use of the [[valueOf]] helper.
 *
 *
 * @example **Create a setter**
 * ```js
 * import muster, { createSetter, query, ref, root, variable } from '@dws/muster';
 *
 * const app = muster({
 *   name: variable('Bob'),
 * });
 *
 * const queryResult = await app.resolve(query(root(), {
 *   setName: createSetter('name'),
 * }));
 * // queryResult === {
 * //   setName: function(val) {...},
 * // },
 *
 * const result = await queryResult.setName('Jane');
 * // result === 'Jane'
 *
 * const name = await app.resolve(ref('name'));
 * // name === 'Jane'
 * ```
 * This example shows how to use the [[createSetter]] to retrieve a function that can be used
 * to imperatively set Muster variables.
