1. Item class

  - Item Data Type 선언 ( data에 key, name, image Frame 등 정보 포함 )

  - Store class 에서 Item 생성시 data를 입력 받는다

  - data를 이용하여 Button 생성 ( Button 객체에 Item texture 설정 )

  - Button Event에 ShowInfo 함수 할당

2. Store class

  - Excel -> tsv 형식으로 만든 txt file을 ifstream 으로 Load

  - Load한 Data를 Item*로 생성, unordered_map 컨테이너에 저장

  - Selected Item Data는 Item class 에서 ShowInfo() 함수로 data 전달 받아 ImGui 이용하여 출력
