[Mono-ue] How do you use GetOverlappingActors?

[Michael Hutchinson]

SubclassOf<T> is analogous to the Unreal TSubclassOf<T> template:
https://docs.unrealengine.com/latest/INT/API/Runtime/CoreUObject/UObject/TSubclassOf/index.html

That said, the "subclass" terminology is confusing and it would
probably make sense for us to rename it to UClass. I've added this to
our task tracker.

This particular method is autogenerated and it looks like the
generator doesn't handle the fact that the classFilter parameter is
optional. I've added this to the tracker too but you should be able to
work around it by using default(SubclassOf<Object>) which would have a
null UClass pointer.
