/* 	How to :
	- NE PAS RENDRE LA CARTE DÉPLAÇABLE. JAMAIS. OU SUBISSEZ UN TAS DE PROBLÈMES.

	- Chaque indice du tableau DC_draggable doit être l'identifiant unique de l'élément à rendre déplaçable sur l'interface de DC.
	
	- Créer un indice du tableau DC_draggable contenant un tableau vide afin faire remonter l'élément au premier plan suite à un appuie sur le clic gauche de votre souris. (CF ligne pour 'zone_centre')
	
	- Créer un indice du tableau DC_draggable contenant un tableau lui-même contentant un indice 'checkbox' afin d'activer la possibilité de déplacement de l'élément. Il faudra, bien-sûr et également, renseigner le code HTML afin qu'il soit rajouter sur l'interface.
	-- le style suivant est obligatoire pour toute div afin d'éviter qu'elle soit cachée ou explose l'apparence normale de la page.
	-- style : "height:0px;width:0px;z-index:999999;"
	-- Vous êtes libre de le compléter ensuite. Ne faites que -modifier le positionnement la div- et/ou -modifier l'apparence de la checkbox-.
	-- Une checkbox avec pour attribut "name" -l'identifiant unique de l'élément à déplacer- et "class" "DC_draggable" est obligatoire (CF code existant).
	
	Enjoy!
