docstr: Creates a reasonable deep structure of S3 subdirectories with files.
  
  Args:
    top_directory: The path of the top level S3 directory in which
      to create the directory structure. Defaults to 'top_dir'.
    ckpt_content: The content to put into model.ckpt. Default to ''.
    region_name: The S3 region name. Defaults to 'us-east-1'.
    bucket_name: The S3 bucket name. Defaults to 'test'.
  
  Returns:
    S3 URL of the top directory in the form 's3://bucket/path'
