Beaucoup modifs cosmétiques et ajouts dans GuiNuMo
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. git-svn-id: https://pif.pu-pm.univ-fcomte.fr/svn/loc@28 785a6c6c-259e-4ff1-8b91-dc31627914f0

|

|

* Area : déf. des zones & waypoints entre les zones. Une zone = 2 points.
|

→ Ajouter au serveur la gestion des connexités entre les zones + graphe qui s'étend (cf. avec les points de référence pour l'algo).
|

→ Faire la fonction qui calcule les matrices étendues en utilisant :
|
||||
° la matrice de distances entre les points de connexité ;
|
||||
° les distances euclidiennes entre les points après FBCM et les points de connexité.
