// AppSessionService ---------------------------------------------------------
// AppSessionService handles session data for apps. It is a sibling of the
// SessionService class which is also based on SessionServiceBase.

// Primarily, the differences between SessionService and this class is that
// AppSessionService does not track things like TabGroups and other things
// that only apply to browser windows.

// In the future, if additional features are required by app restores, those
// features can be moved to the SessionServiceBase and shared by both child
// classes.
