 /**
 * This is a CakePHP helper that helps users to integrate google map v3
 * into their application by only writing php code. This helper depends on jQuery.

 * @author Mark Scherer
 * @link http://www.dereuromark.de/2010/12/21/googlemapsv3-cakephp-helper/
 * @package tools plugin
 * @license MIT License (http://www.opensource.org/licenses/mit-license.php)
 *
 * fixed brackets, spacesToTabs, indends, some improvements, supports multiple maps now.
 * now 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
 *
 * New in v1.4:
 * 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().
 *
 * v1.2: Cake2.x
 * 2011-10-12 ms
 * v1.3: E_STRICT compliant methods (url now mapUrl, link now mapLink)
 * 2012-08-31 ms
 * v1.4: Better handling of script output and directions added
 * 2013-02-24 ms
