A **Manager** is used to manage all incoming and outgoing connections to a server.

On startup all remote servers must be specified.
From that individual connections will be spawned to each remote server,
or incoming requests will be hooked up to the appropriate connection.

To get a connection to a specific server, use `Manager.Connection(host)` to get a connection to the specified host.
From this connection individual requests can be made.
