I need to use Cloneable. (I know that some people say you should never
use it, but it is a requirement of the project.)

I made something I thought should work, but it does not. I have
attached my dumbed down code. What am I doing wrong?

When I in class A change a field from class B in the clone, the field
in the original is also changed. That should not happen.
