//
// author:     Gerald Dherbomez
//
// purpose:    Classe permettant d'enregistrer un fichier de 
//             configuration XML
//             Le fichier XML contient 2 sections : 
//             - parameters : contient les parametres de l'application 
//             - components : contient les composants
//             les composants ne peuvent pas avoir de noeuds fils
//
// todo:       Creer une dtd qui permet de definir la liste des classes possibles
//             que peuvent prendre les composants 
//
