This class essentially converts a Appointment extender into a primary query provider, suitable for use in the Appointment Archive as the root query provider. This is done by having the SetJoin method return a free-standing AppointmentTableInfo instance that is not joined to anything, and overriding the TableToExtend property to return the same TableInfo.
