//
// 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.
