prompt: Your task is to convert the following English description into an ASCII tree format.
  
  mui-utils is a head directory that organizes 2 subdirectories: input and node_modules.
  At the top level, The 'input' storage space sits empty.
  At the top level, 'node_modules' shelters 2 packages: mui-material, mui-utils.
  At level 2, in directory path 'node_modules > mui-material', 'mui-material' encapsulates 1 folders: generateUtilityClass.
  At level 3, in directory path 'node_modules > mui-material > generateUtilityClass', 'generateUtilityClass' contains nothing at present.
  At level 2, in directory path 'node_modules > mui-utils', 'mui-utils' bundles 1 subdirectory elements: generateUtilityClass.
  In nested path 'node_modules > mui-utils > generateUtilityClass', Inside 'generateUtilityClass', you'll find it has been left empty.
  Back to the top level.
