      Provides a way to handle revisions that are to be sent to the client.
      Specified by:
      handleRevisionsBeforeSending in interface IRepository.ReadAccessHandler
      Parameters:
      session - The session that is going to send the revisions.
      revisions - The revisions that are requested by the client. If the client must not see any of these revisions an unchecked exception must be thrown.
