prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  tests
   +--helpers
   |   `--browser
   +--regression
   |   `--libs
   +--test262
   |   `--test262
   `--unit
       `--fixtures
  ```
  
  Convert this description:
  
  crypto is a base directory that houses 3 subdirectories: hash, object-hasher and polyfill.
  At the top level, 'hash' groups 2 contained folders: src, test.
  In nested path 'hash > src', The 'src' directory contains nothing at present.
  In nested path 'hash / test', Inside 'test', you'll find it is unpopulated.
  Back to the top level.
  At the main level, 'object-hasher' encapsulates 2 subdirectory elements: src, test.
  Within directory hierarchy 'object-hasher → src', 'src' has yet to be populated.
  At level 2, in directory path 'object-hasher → test', 'test' has no content.
  Back to the top level.
  At the main level, 'polyfill' maintains 1 subdirectory elements: src.
  At level 2, in directory path 'polyfill > src', Inside 'src', you'll find it hasn't been filled with any content.
  Back to the top level.
