class_docstr: Parameters
  ----------
  data : mapping
      Mapping of keys to column values.
  multiindex : bool, optional
      Whether tuple keys represent a hierarchical
      index with multiple "levels" (default=False).
  level_names : tuple, optional
      Tuple containing names for each of the levels.
      For a non-hierarchical index, a tuple of size 1
      may be passe.
  rangeindex : bool, optional
      Whether the keys should be returned as a RangeIndex
      in `to_pandas_index` (default=False).
  label_dtype : Dtype, optional
      What dtype should be returned in `to_pandas_index`
      (default=None).
