+ * Author: Mike Macgirvin <http://macgirvin.com/profile/mike>
+ *
+ *
+ * Pre-requisite: Register a username at geonames.org
+ * and set in .htconfig.php
+ *
+ * $a->config['geonames']['username'] = 'your_username';
+ * Also visit http://geonames.org/manageaccount and enable access to the free web services
+ *
+ * When plugin is installed, the system calls the plugin
+ * name_install() function, located in 'addon/name/name.php',
+ * where 'name' is the name of the addon.
+ * If the addon is removed from the configuration list, the
+ * system will call the name_uninstall() function.
