prompt: Your task is to convert the following English description into an ASCII tree format.
  
  classes is a principal directory that encompasses 3 subdirectories: __snapshots__, classDeclarations and constructorDeclarations.
  At the top level, '__snapshots__' contains nothing at present.
  At the main level, 'classDeclarations' hosts 3 subdirectories: __snapshots__, classAbstractKeyword, classHeritageSpecification.
  Within directory hierarchy 'classDeclarations / __snapshots__', The '__snapshots__' data structure is currently empty.
  Within directory hierarchy 'classDeclarations / classAbstractKeyword', 'classAbstractKeyword' groups 1 subdirectory elements: __snapshots__.
  In nested path 'classDeclarations / classAbstractKeyword / __snapshots__', The '__snapshots__' directory is blank.
  In nested path 'classDeclarations → classHeritageSpecification', 'classHeritageSpecification' organizes tests across 1 separate subfolders.
  In nested path 'classDeclarations → classHeritageSpecification → __snapshots__', '__snapshots__' is devoid of content.
  Back to the top level.
  At the main level, 'constructorDeclarations' features 1 nested folders: constructorParameters.
  At level 2, in directory path 'constructorDeclarations → constructorParameters', 'constructorParameters' carries 1 nested folders: __snapshots__.
  In nested path 'constructorDeclarations / constructorParameters / __snapshots__', The '__snapshots__' directory lacks any subdirectories.
