Detailed Description

template<EFlag Flag>
class FInstanceAttributeTracker::FDeltaRange< Flag >

Represents the delta range for a given attribute, can either refer to the tracked data or just a span, or be empty. "Added" is always implied & added on top. It is a helper to make it easier to iterate a change set.
