/**
* Module pour utiliser une carte google map
* Ce script necessite que
* - l'api google soit chargée avant l'inclusion de celui-ci
* - le fichier des tranductions soit chargé
* - les variables suivantes soit déclarées
* - gm_icons_informations : Tableau associatif contenant les informations des icones
* - gm_map_name : le nom de l'objet contenant la map
* - gm_directions_name : le nom de l'objet contenant les directions
* - gm_lat_focus : la latitude du focus
* - gm_lon_focus : la longitude du focus
* - gm_zoom_focus : le zoom du focus
* - gm_markers : tableau associatif contenant la liste des latitudes, longitudes et type de marker à utiliser
*
* exemple :
*
*
*
*
*
* La construction de la carte se fait en appelant la fonction gm_makeMap();
