 * The `AddressBook` represents the following DARCs of the `CredentialStruct`:
 * - `credPublic.contacts` as `ABContactsBS` - links to other credentials the user knows
 * - `credPublic.groups` as `ABGroupsBS` - groups the user follows
 * - `credPublic.actions` as `ABActionsBS` - actions, which are DARCs + a coin-instance for actions like login
 *
 * Every field is set up as a `BehaviorSubject`, which means that there is a `getValue()` method to get the current
 * value, but also a `.subscribe()` to be informed if anything changes.
 * If an element is removed or added, the `BehaviorSubject` calls `next` method on all observers.
 * If an element is changed, only the `BehaviorSubject` of this element is updated.
