Hey thanks for the answer.
That doesn’t look like a sample. I’ve checked inside and it’s a big script with mostly internal static methods/structs/classes. I don’t think it’s anywhere near an example. Appreciate the effort but doesn’t look like something usable sadly 
Obviously it can be dissected and be used in the end to create something of our own but that is way too much effort up to a point where makes using the sprite atlas system meaningless anyways.
Still tho, thanks for the answer.
