+// The sole purpose of this class is to take attachment
+// requests, queue them up, and send them all at once.
+// This handles situations where the viewer may request
+// a bunch of attachments at once in a short period of
+// time, where each of the requests would normally be
+// sent as a separate message versus being batched into
+// one single message.
+//
+// The intent of this batching is to reduce viewer->server
+// traffic.
