   #| CHANGED :ACCESSOR VALUE FROM TUTORIAL (CHAPTER 4)
   ===================================================
   The Chapter 4 tutorial has the :accessor value set to
   'administratorp'. Unfortunately, this causes initialisation
   argument errors when trying to seed the database. To fix this, I
   had to remove the 'p' part from that line. At the time of
   writing, I do not know if that will have a negative effect on
   future tutorials.

   I have left a note in the 'seeds' function below highlighting the
   change to the :accessor value.

		  :boolean
		  :initarg
		  :administrator
		  :initform nil
