prompt: Your task is to convert the following English description into an ASCII tree format.
  
  simple.git is a base directory that includes 3 subdirectories: logs, objects and refs.
  At the main level, 'logs' keeps 1 nested folders: refs.
  In nested path 'logs → refs', 'refs' keeps 1 child directories: heads.
  At level 3, in directory path 'logs → refs → heads', The 'heads' folder has no content.
  Back to the top level.
  At the main level, 'objects' carries 3 contained folders: 4b, 6f, d1.
  In nested path 'objects > 4b', Inside '4b', you'll find it awaits content.
  Within directory hierarchy 'objects > 6f', Inside '6f', you'll find it has nothing inside.
  Within directory hierarchy 'objects → d1', Inside 'd1', you'll find it is empty.
  Back to the top level.
  At the main level, 'refs' keeps 1 child directories: heads.
  In nested path 'refs > heads', The 'heads' folder contains no subdirectories.
  Back to the top level.
