Subject: [PATCH] =?UTF-8?q?Beaucoup=20modifs=20cosm=C3=A9tiques=20et=20ajo?=
 =?UTF-8?q?uts=20dans=20GuiNuMo?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Partout où cela était possible :
* Indentation "Emacs" du code, aération.
* Utilisation de #define pour les valeurs par défaut.
* Utilisation des valeurs par défaut dans les constructeurs.

server.cc/hh :
* Gestion d'erreur basique pour les ouvertures de fichiers.

Ajout du TODO, d'après celui fait par Fred sous format papier.

Création des répertoires :
* cfg : fichiers de configuration.
* csv : fichiers d'entrée.
* log : fichiers de sortie.
