+/*
+ * ACL selector json backend 
+ * This module provides JSON lists of connections and local/remote channels
+ * (xchans) to populate various tools such as the ACL (AccessControlList) popup
+ * and various auto-complete functions (such as email recipients, search, and 
+ * mention targets.
+ * There are two primary output structural formats. One for the ACL widget and
+ * the other for auto-completion.
+ * Many of the  behaviour variations are triggered on the use of single character keys
+ * however this functionality has grown in an ad-hoc manner and has gotten quite messy over time.
