 * ********************************************************************************** *
 * Mode d'emploi :																	  *
 *	- Copier _Console.cs dans le dossier de votre projet							  *
 *  - Ajouter _Console.cs à votre projet (Menu Projet, Ajouter un composant existant) *
 *  - Utiliser _Console à la place de Console (ex: _Console.WriteLine("Coucou");)     *
