/**
 * This hook provides utilities to act on a {@link UCOutputReader} in a React way
 *
 * A usual scenario of this is a "CRUD-like" UI displaying multiple use cases :
 *
 *   - A `List` use case to display a collection of items
 *   - A `Create` use case to add an item
 *   - A `Delete` use case to remove an item
 *   - An `Update` use case to update an item
 *
 * Whenever one of this use case is performed, you can use the `ucor` to act on the main UCOR in an immutable way.
 *
 * @param ucor
 * @returns
