/*
 * Interface for message bridges.
 *
 * A message bridge connects a message bus with another messaging system. It is really just a regular
 * message endpoint connected to a message bus that translates sent and received messages between the bus
 * and some underlying transport technology. The transport technology is usually implemented in the form of a 
 * Message Transport Plug-in, such as the UdpMessaging plug-in that ships with Unreal Engine.
 *
 * The most common use case for message bridges is to connect two Unreal Engine message buses running in
 * separate processes or en different computers. Another common use case is to connect an Unreal Engine
 * message bus to an entirely different messaging system that is not based on Unreal Engine.
 *
 * Message bridge instances can be created with the IMessagingModule.CreateBridge method.
