* A WhitelistRule is used to determine if an API call is authorized.
* For example:
*
- * @code
+ * ```
* new WhitelistRule(array(
* 'entity' => 'Contact',
* 'actions' => array('get','getsingle'),
* 'required' => array('contact_type' => 'Organization'),
* 'fields' => array('id', 'display_name', 'sort_name', 'created_date'),
* ));
- * @endcode
+ * ```
*
* This rule would allow API requests that attempt to get contacts of type "Organization",
* but only a handful of fields ('id', 'display_name', 'sort_name', 'created_date')
