[복습] LearnUGUI - Practice05 [Shop], DataManager로 데이터 받아오기

너무 이해가 안되서 천천히 생각하면서 계속 반복반복했다.

처음에는 UIChestScrollView가 무슨 역할인지도 이해가 안됐는데 그나마 이해가 되고

DataManager- LoadChestData함수의 역직렬화도 GetChestData의 ToList로 데이터를 return 하는 것도 보다보니 익숙해진다.

그래도 이해가 잘 되진 않아서 계속 연습해야할 것 같다.

특히 AtlasManager는 다른 것도 벅찬데 이것도 이해하려면 잘 모르겠어서 그냥 적고 패스했다..
