Christian, this is far from standard. It's fairly discombobulated
scratch work. The objects aren't even classes.
If you look for the cell that starts out:
CatCat = CatalanCatalog()
CatCat.add_type('c','binary tree',...
and execute that, then things should work better for you. The
relevant cells are marked #auto, but apparently there's a bug in that,
too.
