+# MTranslator permet de realiser une animation de translation sur l'objet
+# 
+# proprietes :
+#	* -visible : permet d'activer ou non l'animation
+#	* from_x, from_y : valeur initiale de la transformation
+#	* to_x, to_y : valeur finale de la transformation
+# 	* duration : duree de l'animation
+#	* loop : marque le caractere repetitif ou non de l'animation
+#	* targets : objets cible de cette animation
+# Evenements :
+#	* ANIMATION_END : Notifie lorque l'annimation se termine
+#	* MOTION : Notifie lorsque la valeur de l'opacite est changee au cours de l'animation
+#	* ANIMATION_ABORD : Notifie lorsque l'animation est stoppee avant la fin
+# Fonctions : 
+#	* start : demarre l'animation
+#	* stop: arrete l'animation
+#	* isRunning : test si l'animation est en cours
