Greetings.

Modified the patch as requested: the ordering in the documentation is
now "Column formulas" before the new "Lookup functions".

Also made org-table.el (require 'cl) in general, not only compile time,
because there was a warning of it being required at runtime, but there
is still a warning at compile time. Seemed like a reasonable thing to
do, although given the discussion on possible namespace clashes on the
net makes me doubt the approach. It seems GNU does not like CL. I can
implement a new function corresponding to CL's "position" if you find it
necessary.

Have fun.
