Create MrPing and MrPong Actors

With the help of Content Assist create two new actor classes and name them MrPing and MrPong. The resulting model should look like this:

RoomModel SendingData {

    LogicalSystem SendingData_LogSystem {
        SubSystemRef SendingDataAppl: SendingData_SubSystem
    }

    SubSystemClass SendingData_SubSystem {
        ActorRef SendigDataTopRef: SendingDataTop
    }

    ActorClass SendingDataTop { }

    DataClass DemoData {
        Attribute int32Val: int32 = "4711"
        Attribute int8Array [ 10 ]: int8 = "{1,2,3,4,5,6,7,8,9,10}"
        Attribute float64Val: float64 = "0.0"
        Attribute stringVal: string = "\"empty\""
    }

    ProtocolClass PingPongProtocol {
        incoming {
            Message ping(data: DemoData)
            Message pingSimple(data: int32)
        }
        outgoing {
            Message pong(data: DemoData)
            Message pongSimple(data: int32)
        }
    }

    ActorClass MrPing {
        Interface { }
        Structure { }
        Behavior { }
    }

    ActorClass MrPong {
        Interface { }
        Structure { }
        Behavior { }
    }
}
