/**
 * WebObjects wrapper for INGoogleMap.js.
 *
 * <p>
 * CCGoogleMap replaces AjaxGmap and will allow you to easily insert a google map inside your page</p>
 * <p>
 * You must set the property ajax.google.maps.V3.apiKey in your Properties file</p>
 *
 * <p>please note that is REQUIRED to set the widht height of the map, you can use id, class, or style to do that</p>
 * 
 * @binding id the id of the div element that CCGoogleMap will generate
 * @binding class the class of the div element
 * @binding style the style of the div element
 * @binding zoom the desidered map startup zoom level
 * @binding the address of the marked, formatted for google, like: 1 Infinite Loop, Cupertino CA, United States
 * @binding lat the latidude of the map center. if lat and lng are specified they will override the address lookup
 * @binding lng the longitude of the map center. if lat and lng are specified they will override the address lookup
 * @binding type, can be ROADMAP, SATELLITE, HYBRID or TERRAIN, default to ROADMAP. all uppercase string
