(vocabulary_path)
Initialize vocabulary from file.

  We assume the vocabulary is stored one-item-per-line, so a file:
    dog
    cat
  will result in a vocabulary {"dog": 0, "cat": 1}, and this function will
  also return the reversed-vocabulary ["dog", "cat"].

  Args:
    vocabulary_path: path to the file containing the vocabulary.

  Returns:
    a pair: the vocabulary (a dictionary mapping string to integers), and
    the reversed vocabulary (a list, which reverses the vocabulary mapping).

  Raises:
    ValueError: if the provided vocabulary_path does not exist.
