A ZClass doesn't need to be contained in another ZClass
in order to inherit from it. For example, let's say you
create a Product called "SpamCan". Inside of SpamCan,
you can create a "Findable" ZClass. After adding that,
you can create a "SpamCan" ZClass and "Findable" should
show up in the list of possible base classes when you
define SpamCan. It should also show up in the bases list
if you try to create more ZClasses _inside_ of the SpamCan
class.

Hope this helps!
