hub_create(+Name, -Hub, +Options) is det

Create a new hub. Hub is a dict containing the following public information:

Hub.name: The name of the hub (the Name argument)
queues.event: Message queue to which the hub thread(s) can listen.

After creating a hub, the application normally creates a thread that listens to Hub.queues.event and exposes some mechanisms to establish websockets and add them to the hub using hub_add/3.
