class_docstr: Generic class to download the pre-trained models
  
  Usage Example:
  
  chunker = ChunkerModel.get_instance()
  chunker2 = ChunkerModel.get_instance()
  print(chunker, chunker2)
  print("Local File path = ", chunker.get_file_path())
  files_models = chunker2.get_model_files()
  for idx, file_name in enumerate(files_models):
      print(str(idx) + ": " + file_name)
