// ce que doit renvoyé un module
//1 - les routes, enfin le router avec des routes definis
//2 - les methodes du controler ou par defaut une classe controleur
//3 - pareils pour le modele/schemma mongoDB

//Pourquoi ?
//1 bah en fait les route y'en a pas vraiment besoin mais faut pour les lancer et les modifier
//2 elle doivent etre accessible pour pouvoir etre utilisé par d'autre modules
//3 aussi pour etre utiliser par d'autre modules

//donc concretement ...
// solution A
//unModule = {
//    router: {},
//    controler: {},
//    schema: {}
//}
