Started making potatoes.

We now have two types of potatoes.  What else should the potato types
contain, I wonder.

Potato types have been added, we have five now.  Is that enough?  The
world may never know.

Can has squashed commits?
Added five types of potatoes which extend the potato class, and another
method to the tuber interface, since there are two types of tubers.  Also
fixed a couple spelling errors.
