// ListenerFunc is a single listener function that implements the
// gumble.EventListener interface. This is useful if you would like to use a
// type-switch for handling the different event types.
//
// Example:
//  handler := func(e interface{}) {
//    switch e.(type) {
//    case *gumble.ConnectEvent:
//      println("Connected")
//    case *gumble.DisconnectEvent:
//      println("Disconnected")
//    // ...
//    }
//  }
//
//  client.Attach(gumbleutil.ListenerFunc(handler))
