ISSUE: getHubID/getSelfID

Hi,

As they are indeed 2 *special* client-ids, I think it makes sense to
have methods allowing to easily retrieve them.

I don't like the idea of dictating an ID for the hub. It is much cleaner
to have a getHubID method, and this should not put any unbearable
additional burden on hub developers.

I think we can have both. The register method could return a map with
keys 'private-key' and 'public-id' along with the corresponding values.
