* Create example for apub lib * some rewriting of apub lib * Add LocalInstance struct for apub lib to avoid using Lemmy Settings * Move ActorType trait to lemmy_apub, because its not needed in library * Use reqwest_retry instead of custom impl, dont specify timeout on every send() * Some improvements to example * Moved inbox handling to library * bug fixes * Move context and serde helpers into library * wip: example changes * Add lemmy_utils feature to build only LemmyError * Rename to activitypub_federation * Remove lemmy_utils dep from activitypub_federation using generic error type * Finish activitypub example * Cleanup and fix tests * Reorganize library files * Remove ApubObject.to_tombstone() * Extract activitypub library into separate git repository
