 * Plugin for jQuery 1.1 to manage Google Maps

 *
 * the method wait locations data as JS Object with this structure:
 *
 * data: {locations: [
 * 	{
 *  	simpleContent: String with the HTML content in the info window.
 * 		maximizedContent : URL of the HTML page (AJAX loaded) of the maximized info window.
 * 		latitude: latitude of the geographic poing (you can use infopanel for obtain that)
 * 		longitude: longitude of the geographic poing (you can use infopanel for obtain that)
 * 		zoom: zoom level for hotspot links
 * 		icon: url of the custom icon for this place
 *  },
 *  ...
 * ]}
 * 
 * The "infopanel" param is a DOM object to show the latitude and longitude of the
 * center of the map, also, the level zoom applied.
 * 
 * The "maptype" param is some of map type that admits Google MAPS like G_MAP_TYPE, G_SATELLITE_TYPE y G_HYBRID_TYPE.
 * 
 * The "center" param is a point [latitude, longitude of the default point of the map center
 * 
 * The "zoom" param is the default zoom applied
 * 
 * The "relativepath" param is the absolute url folder path of the document (used for relative paths
 * of icons and maximized content).
 * 
 * sample:
 * $("#mylayer").gmaps({
 * 	data: myplaces, 
 * 	infopanel: $("#infolayer").get(0), 
 * 	tipomapa: G_HYBRID_TYPE,
 *  centro: [1, -0.3],
 *  zoom: 10,
 *  relativepath: "http://mydomain.com/myproject/"
 * });
