/*
Pour ajouter un lien qui ouvre une popUp il faut simplement ajouter à l’élément la class ‘openPlan-ville’. Une fois ajouté l’élément devient cliquable et ouvre une "popUp" avec par défaut laville de Lausanne. Il est possible d’ajouter les attributs suivants pour obtenir un affichage personnalisé. 

data-adresse 		ex: data-adresse= "Route de chavannes, 15"
data-zoom			ex: data-zoom = "12"
data-latlng			ex: data-latlng = "46.5415, 5.48552"

data-texteBulle		ex: data-textinfo = "Un text d'info qui apparait dans une bulle quand l'utilisateur cliue sur un marker"
data-bulleVisible	ex: data-bulleVisible = "1" (par défaut la bulle n'est pas visible)
data-alt			ex: data-alt = "Un texte qui apparait quand l'utilisateur laisse la souris sur un marker"


exemple:
<a class="openPlan-ville" data-zoom="15" data-adresse="Route de chavanne, 15">Mon lien vers la carte</a>
