prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  request
   +--examples
   +--lib
   `--tests
       +--browser
       |   `--ssl
       +--fixtures
       `--ssl
           `--ca
  ```
  
  Convert this description:
  
  history is a base directory that encompasses 3 subdirectories: __mocks__, __tests__ and src.
  At the top level, Inside '__mocks__', you'll find it is an empty container.
  At the main level, '__tests__' houses 1 folders for testing purposes.
  Within directory hierarchy '__tests__ → __snapshots__', The '__snapshots__' container is unpopulated.
  At the top level, 'src' encapsulates 2 subdirectories that organize the source code.
  In nested path 'src → history', Inside 'history', you'll find it is blank.
  In nested path 'src → operation', 'operation' is currently empty.
  Back to the top level.
