## Interface GatewayReceiver

-     public interface GatewayReceiver

  A GatewayReceiver that receives the events from a `GatewaySender`. GatewayReceiver is used in conjunction with a `GatewaySender` to connect two distributed-systems. This GatewayReceiver will receive all the events originating in distributed-systems that has a `GatewaySender` connected to this distributed-system.
