Ted means that you do it like this:


	----> +d.sex

	MALE   -- Homer -- Bart -- Barney -- Moe -- Ned -- Snake



	FEMALE -- Marge -- Lisa -- Maggie


Then if you are sitting on a cell, say `Ned', and you want to know
whether Ned is male or female, you move in the -d.sex direction as far
as you can, and the cell that you finally come to tells you the
answer.  This cell is the `headcell'.
