* A wired network is composed of one of more {@link IWiredNode}s, a set of connections between them, and a series
* of peripherals.

* Networks from a connected graph. This means there is some path between all nodes on the network. Further more, if
* there is some path between two nodes then they must be on the same network. {@link IWiredNetwork} will automatically
* handle the merging and splitting of networks (and thus changing of available nodes and peripherals) as connections
* change.
*
* This does mean one can not rely on the network remaining consistent between subsequent operations. Consequently,
* it is generally preferred to use the methods provided by {@link IWiredNode}.
