This chapter is now complete. When I uploaded it, I got a warning that it was too big for one page so I split it in half. I probably didn't split it at the best place! Perhaps someone else could check and repartition it if necessary.
Btw the published version has a spelling mistake on p.27: "polyons" instead of "polygons". -- Hazel Russman <[email protected]> -- ------------------------------------------------------------------------ To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] with Subject: help
