prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  custom_resolve_dir
   +--testproj
   |   `--__snapshots__
   `--testproj2
       `--__snapshots__
  ```
  
  Convert this description:
  
  ref is a core directory that incorporates 6 subdirectories. Notable ones include class-based-views, contrib, files among others.
  
  Let me break down the organization for you:
  
  At the top level, The 'class-based-views' directory is currently empty.
  At the top level, 'contrib' keeps 3 nested folders: admin, gis, postgres.
  At level 2, in directory path 'contrib → admin', 'admin' comprises 1 contained folders: _images.
  Within directory hierarchy 'contrib → admin → _images', '_images' stands empty.
  In nested path 'contrib → gis', 'gis' comprises 1 subdirectories: install.
  At level 3, in directory path 'contrib > gis > install', 'install' is vacant.
  In nested path 'contrib / postgres', 'postgres' hasn't been filled with any content.
  Back to the top level.
  At the top level, Inside 'files', you'll find it contains nothing at present.
  In the root directory, 'forms' is an empty container.
  At the main level, 'models' is empty.
  At the top level, Inside 'templates', you'll find it has no content.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
