[fitsbits] WCS Coordinates Paper III

[Eric Greisen]

While many of you were ADASSing in France, Steve Allen and I were busy
rethinking the section on the -TAB non-linear algorithm.  Nothing
substantive was changed, but the nomenclature and descriptions have
been greatly improved and an illustrative example added.

I encourage you to visit my web site and download the current version
(dated today):

We are thinking of submitting the paper soon for publication in A&A
and for ratification by the FITS committees.  If you do not make
comments soon you will have lost your chance.
