-# Reseau de Petri
-binome 2 Sean/Amaury
-
-## Note de conception
-Nous avons procédé à quelques modification par rapport a notre conception initiale.
-
-Ainsi nous avons ajouté une methode *equals* aux classes arc et place. Ces methodes servent pour deleteArc() et deletePLace()
-
-Nous avons également rajouté des methodes *toString* afin d'avoir une meilleur visibilité pour nos tests.
-
-Nous avons aussi déclaré des constante ArcEntering, ArcOutering, qui sont des entier pour que lors de la declaration des arc le choix soit clair.
-
-## Execution du code
-Nous avons réalisé des tests Junit pour chaque classe et leurs methodes réspectivent. Pour les excuter il *faut executer src as a Junit test*. Nous avons a chaque fois testé chaque methodes. Mais les tests ne sont sans doute pas exaustif.
-Lorsque on fait cela on voit **4 erreurs**, en effet,les test des différent classe de Arc (ArcOutering,...) ne sont pas "relier" a leur test mais ces classes sont **bien tésté**.
-
-En executant src *as a Java Application*, on voit un exemple simple de réseau de petrie
-
-Nous n'avons pas encore rajouté la JDOC
