/**
* Get action Links.
*
+ * @todo:
+ * While this function only references static self::$_links, we can't make
+ * the function static because we need to match CRM_Core_Page_Basic. Possibly
+ * the intent was caching, but there's nothing very time-consuming in here
+ * that needs it so do we even need $_links? The variable is public - a quick
+ * look doesn't seem like it's used on its own, but it's hard to fully check
+ * that.
+ *
* @return array
* (reference) of action links
