This is a simple "example" type program.  It includes a generic
Tree class and it shows examples of things like:

* simple handling of multiple documents
* subclassing an AppKit control
* associating a file type (".tree") with an application
* drawing lines with PostScript (I did it the easiest and
    slowest way, but it works)
* using the List class (including using it as a stack)

and who knows what all else.

It's free, and you can do what you want with the source.

Enjoy!
