I'm looking through the Collections API, but not finding exactly what I 
want... hoping someone who's more familiar with it can point me in the right 
direction.

What I'm trying to do is more or less what you see on catalog sites where 
they'll list the most recent items you've looked at, newest on top.  So it's 
ordered (List), but has no duplicates (Set), and I need to have a  max size.

ListOrderedSet is almost there, except that it retains the 'old' position if 
you add the same item again.  (And has no max length.)

So... before I either write it myself or extend ListOrderedSet to make it do 
what I want, does anyone have another suggestion?  And what would _you_ call 
it?

Thanks,
Wendy Smoak
