Objective-C doesn't generally use the term "derived" (for example, see archive of [Programming With Objective-C > Defining Classes](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/ProgrammingWithObjectiveC/DefiningClasses/DefiningClasses.html#//apple_ref/doc/uid/TP40011210-CH3-SW1)). With that said, I don't think it's unreasonable or incorrect to use the term "derived" to describe inheritance in Objective-C. The behavior of this matcher is also consistent with the behavior of `isDerivedFrom`. In order to change `isDerivedFrom`, I would also need to update `isSameOrDerivedFrom`. That would probably be a good thing so that derivation matching feature set is consistent for C++ and Objective-C language variants. Let me take a crack at merging this into `isDerivedFrom`.
