[split] CI4 vs CI3/CI2

Pertti, something like Entities already exists in CI3

Wowzers, did not know that!

I've also managed to get few things mixed up, as I thought from memory that in CI4 the entities gave you ORM capability.

Which looks like is actually part of Model features, but also part Entity features. Hmm... looks like this guy needs to spend a his lunchbreak reading through CI4 documentation again
