1. How will your ZTRowIterator represent the coordinates in a
ZoomTable that are in between two actual Nodes in a row? What happens
when you increment?

2. After you increment a ZTRowIterator, how can you check if you
have gone past the last column?

3. How will your ZTRowIterator * (dereference) operator know
when it should return the default value?
