extends Object
implements Iterator
A class that implements a BottomUpTreeWalk Example of use of the Iterator:
    Tree tree;
    ...
    for ( BottomUpTreeWalk i = tree.beginBottomUp(); !i.atEnd(); i.advance() )
      if ((Tree)i.get().arity().atomp())
        System.out.println((Tree)i.get().operator_name()+" "+(Tree)i.get().atom_value());
      else
        System.out.println((Tree)i.get().operator_name());
