class ProtectedPrivatesSubclass in Examples for Developers 3.x

A class for testing ProtectedPrivate::protectedAdd().

We could use reflection to test protected methods, just as with private ones. But in some circumstances it might make more sense to make a subclass and then run the tests against it.

This subclass allows us to get access to the protected method.
