27 * The identity manager takes care of loading and storing identities, their
28 * contexts, and properties. It does so in a way that does not expose errors via
29 * exceptions but it only logs them and tries to return sensible defaults.
32 * It is also responsible for polling identities from the Web of Trust plugin
33 * and sending events to the [EventBus] when [Identity]s and
34 * [OwnIdentity]s are discovered or disappearing.
