`Node(dir: Path, p2pAddr: <ERROR CLASS>, webServerAddr: <ERROR CLASS>, configuration: NodeConfiguration, networkMapAddress: NodeInfo?, advertisedServices: Set<ServiceType>, clock: Clock = NodeClock())`

A Node manages a standalone server that takes part in the P2P network. It creates the services found in ServiceHub, loads important data off disk and starts listening for connections.

### Parameters

`dir` - A Path to a location on disk where working files can be found or stored.
`p2pAddr` - The host and port that this server will use. It cant find out its own external hostname, so you have to specify that yourself.
`configuration` - This is typically loaded from a .properties file.
`networkMapAddress` - An external network map service to use. Should only ever be null when creating the first network map service, while bootstrapping a network.
`advertisedServices` - The services this node advertises. This must be a subset of the services it runs, but nodes are not required to advertise services they run (hence subset).
`clock` - The clock used within the node and by all protocols etc.
