/**
 * Renvoie certaines méthodes pour interagir avec les menus
 *
 * La méthode `buildMenu` permet de construire un menu ou un sous-menu.
 * Elle prend en paramètre n'importe quelle subclass de AbstractMenuBuilder
 *
 * La methode `hasMenu` permet d'interroger le store pour savoir si un menu portant ce nom a été
 * construit pour l'utilisateur courant, et si ce menu n'est pas vide.
 *
 * Fournit aussi des méthodes pour créer directement les principaux types de menus :
 *
 *   - buildMainMenu
 *   - buildConfigurationMenu
 *   - buildAccountMenu
 *   - buildMyAccessesMenu
 *   - buildMyFamilyMenu
 *   - buildWebsiteListMenu
 *   - buildParametersMenu
 *
 *
 * Exemple d'usage :
 *
 *     const { buildMenu, hasMenu } = useMenuBuilder()
 *     const menu = buildMenu(MainMenuBuilder)
 *
 *     console.log(hasMenu('Main')) // true
