+# Le composant MTimer encapsule la d?claration et l'utilisation d'un timer.
+# Les param?tres :
+# 	* $timeout : repr?sente timeout en ms du timer (totologique ? non...)
+#	* $repeat : active ou non le caract?re r?p?titif du timer (valeur 0 ou 1)
+#	* $callback : est optionnel et permet d'appeler une callback au timeout.
+# Les ?v?nements :
+#	* TIME_OUT : ?mis au timeout en plus de l'appel ? une ?ventuelle callback
+#	* TIMER_STOPPED : ?mis si le timer est interrompu avant un timeout
+# Les propi?t?s :
+#	* timeout : ...
+#	* repeat : ...
+#	* callback : ...
+#	* -visible : d?finie pour assurer la compatibilit? avec les autres objets MTools. 
+# 	Si la valeur est 0 le composant est d?sactiv? (appel ? la fonction stop),
+#	si la valeur est 1 (appel ? la fonction start), le composant est activ?.
+#	Cette propri?t? permet notamment d'activer un timer dans un ?tat d'un MSwitch.
+# Les fonctions public :
+# 	* start permet de d?marrer le timer
+# 	* stop permet de stopper le timer
+#	Nota : cf. ci-dessus, ces fonctions peuvent ?tre contr?l?es par la propri?t? -visible
