download all net
mark all unit as a net
The goal : save the whole network to solve the problem of fast update of Internet information and burning after reading; to mark the network to solve the loss of network individual attributes (for example, all sites under a malicious developer should be marked with the attribute of danger) Since it is a personal network, we should implement the whole system by ourselves, so as to avoid the direct change of the system by other parties.
保存整个网络
标记所有的单元形成一个网络
目标为：保存整个网络用于解决互联网信息更新快阅后即焚的问题；标记网络用于解决网络个体的属性丢失（如一个恶意开发者下的所有站点都应该被标记有危险这一属性）
既然是个人保存的网络，即应当自行实现整个系统以免其他方对系统的直接更改。
