tictoc 10 几个模块连接，发送消息直到模块3收到消息

1. 让我们用几个(n)’ tic’模块让它更有趣，并将每个模块连接到其他模块。
2. 把它们的工作简单化:模块0生成一条消息，其他模块继续向随机方向传递消息，直到它到达模块2。

tictoc 11 新增信道定义

1. (实现内容同上)让我们用几个(n)’ tic’模块让它更有趣，并将每个模块连接到其他模块。现在，让我们把它们的工作简单化:模块0生成一条消息，其他模块继续向随机方向传递消息，直到它到达模块2。
2. 信道使用本地信道类型定义，减少连接冗余

types://定义信道
        channel Channel extends ned.DelayChannel {
            delay = 100ms;
        }
