Long-lived permissions not implement ?

Hi,

Thanks for making this java client to connect to orcid rest api. It's very usefull.

But it seems that we can't enabling automatic updates (http://members.orcid.org/api/news/orcid-api-enabling-automatic-updates). Indeed, to create a token, we need authorization code and it's not necessary with the long-lived permissions.

Does I've missed something in the API implementation or I've right ?
