[Haskell-cafe] New (simple) Lazy Evaluation tutorial

[Andrew Wagner]

Hi all,

An interesting question came up in #haskell the other day, and I took
the resulting discussion and wrapped it up into a simple tutorial for
the wiki. Since I'm quite a newbie to haskell myself, I'd appreciate
any double-checking of my logic and, of course, any other
comments/suggestions. Thanks to Cale for his efforts on this problem,
and to the original asker, whose name I can't recall.
