Registering an addressbook in a type index when created

[SharonStrats]

Currently there doesn't appear to be any registration of an address book when created. I have looked in inbox, preferences, public type index and private type index.

In working on this issue in profile-pane SolidOS/profile-pane#9, I need a way to find a users address books so I can present them as a place to store the contact.

I'm also allowing the user to create an address book and I'm not sure where I should register the address book so that I can find it again.

Also, I'm not sure if it's important to mention, but just in case ... I'm trying to use https://github.com/solid-contrib/data-modules to read and write the address data and here it doesn't add a public address to a type index, but a private address it adds to the private type index.

After talking to Timea and Angelo I realized not everyone will want their address book in their type index for it to be found by others. But it would be good to allow the user to have the option to add. If it's a public address book it would be written to the public type index and if it's a private address book it would be written to the private index. Presenting to the user as "Findable" versus the type index wording so it's easy to understand by those who don't know about the type indexes.

It seems to me there is under the new Sharing button, besides the sharing pane also a pane for findable in type index or not. The call is:
UI.login.registrationControl(sharingContext, book, ns.vcard('AddressBook')) .then(() => debug.log('Registration control finished.')) .catch(e => UI.widgets.complain(sharingContext, 'registrationControl: ' + e)) }) in contactsPane.js
The wording on it is off and needs improvement in solid-ui but the feature seems to exist.
