begging for a tree implementation

[Micah]

I'm looking for a simple tree implementation: 0-n children, 1 root.
All the nice methods would be appreciated (getLeaves, isLeaf, isRoot,
depthfirst, breadthfirst,...)  That's really all I need.  I could code
one up, but it would take time to debug, and i'm really short on time
right now.

Thanks!
Micah
