Description
Appends ranges of the given FMassArchetypeEntityCollection instance. Note that it can be safely done only when both collections host entities of the same archetype, and both were created with the same version of said archetype. Additionally, we don't expect the operation to produce overlapping entity ranges and this assumption is only verified in debug builds (i.e. use it only when you're certain no range overlaps are possible).
