Well, it's just me teaching my kid recursion in c, so it's kind of informal
and I'm just clearing the screen to repaint it a second later with
changes. It's too bad that curses adds so much overhead. I'll have to
compare the resultant a.outs to confirm exactly how much.. Not that it
matters for a play program, really, more of a curiosity..
Thanks again Mary Ann!
