+ * 
+ * @param $assigned
+ *  An array of key=>value pairs in the format of uid=>name that represent
+ *  the list of users that the issue may be assigned to. This parameter
+ *  is passed by reference so the hook may make changes, such as adding or
+ *  removing elements.
+ * @param $node
+ *  The node object for the issue being edited or commented on. The hook may
+ *  use the node's information in order to determine which users to add to or
+ *  remove from the list of potential assignees.
+ * @return
+ *  None.
