tree view hide key

[Mike Kerner]

• Nodes can't have both keys and values, only leaves can
• You can't hide the key
• Hiding the key is kind of important if you're trying to use it for a
directory tree view.  Working around this requires assigning keys only but
no values, but if you do that then you can't figure out (without looking at
the array) whether you are dealing with a leaf or a node.

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
