I'd like a function that throws out duplicate entries in a list and keeps
the
original list order.  (when it sees 2 equal entries it throws out the one
that is later in the list).   I'd use Union, but it sometimes changes the
order of the elements in the list.  What's the tersest way to do this?
Thanks in advance,
Dave Snead
