/**
 * This is a CakePHP helper that helps users to integrate GoogleMap v3
 * into their application by only writing PHP code. This helper depends on jQuery.
 *
 * Capable of resetting itself (full or partly) for multiple maps on a single view.
 *
 * CodeAPI: http://code.google.com/intl/de-DE/apis/maps/documentation/javascript/basics.html
 * Icons/Images: http://gmapicons.googlepages.com/home
 *
 * @author Rajib Ahmed
 * @author Mark Scherer
 * @link http://www.dereuromark.de/2010/12/21/googlemapsv3-cakephp-helper/
 * @license MIT License (http://www.opensource.org/licenses/mit-license.php)
 * @version 1.5
 *
 * You can now either keep map() + script(), or you can now write the script to the buffer with
 * map() + finalize(). You can then decide wether the JS should be in the head or the footer of your layout.
 * Don't forget to put `echo $this->Js->writeBuffer(array('inline' => true));` somewhere in your layout then, though.
 *
 * You can now also add directions using addDirections().
 * Markers can be open now by default on page load. Works for both single and multi window mode.
