+ * User Picker.  Sends an array of user guids.
+ *
+ * @package Elgg
+ * @subpackage Core
+ *
+ * @uses $vars['value'] Array of user guids for already selected users or null
+ *
+ * The name of the hidden fields is members[]
+ *
+ * @warning Only a single input/userpicker is supported per web page.
+ *
+ * Defaults to lazy load user lists in alphabetical order. User needs
+ * to type two characters before seeing the user popup list.
+ *
+ * As users are selected they move down to a "users" box.
+ * When this happens, a hidden input is created with the
+ * name of members[] and a value of the GUID.
