/// This is a template for root actors.
///
/// We qualify a `root actor` as the root of an actor hierarchy.
///
/// Note that there are only two root actors in the current implementation:
///
///   * The `user actor` which is the root for all user created actors.
///   * The `system actor` which is the root for all actors created for the actor system.
///
/// The father of these two actors is Cthulhu.
