docs: Create unique file name within a jobStore directory or tmp directory.
  
          :param fileName: A file name, which can be a full path as only the
          basename will be used.
          :param jobStoreID: If given, the path returned will be in the jobStore directory.
          Otherwise, the tmp directory will be used.
          :param sourceFunctionName: This name is the name of the function that
              generated this file.  Defaults to x if that name was not a normal
              name.  Used for tracking files.
          :return: The full path with a unique file name.
