// Actor represents ActivityPub's actor concept. It conceptually has an inbox
// and outbox that receives either a POST or GET request, which triggers side
// effects in the federating application.
//
// An Actor within an application may federate server-to-server (Federation
// Protocol), client-to-server (Social API), or both. The Actor represents the
// server in either use case.
//
// An actor can be created by calling NewSocialActor (only the Social Protocol
// is supported), NewFederatingActor (only the Federating Protocol is
// supported), NewActor (both are supported), or NewCustomActor (neither are).
//
// Not all Actors have the same behaviors depending on the constructor used to
// create them. Refer to the constructor's documentation to determine the exact
// behavior of the Actor on an application.
//
// The behaviors documented here are common to all Actors returned by any
// constructor.

// POST to an actor's inbox. If false, the request was not an
// ActivityPub request and may still be handled by the caller in

//
// If the error is nil, then the ResponseWriter's headers and response
// has already been written. If a non-nil error is returned, then no
// response has been written.
//
// If the Actor was constructed with the Federated Protocol enabled,
// side effects will occur.
//
// If the Federated Protocol is not enabled, writes the
// http.StatusMethodNotAllowed status code in the response. No side
// effects occur.

// - A new ID is generated for the activity.
// - The activity is added to the specified outbox.
// - The activity is prepared and delivered to recipients.
