docstr: Add a dataframe describing vertex properties to the PropertyGraph.
  
  Parameters
  ----------
  dataframe : DataFrame-compatible instance
      A DataFrame instance with a compatible Pandas-like DataFrame
      interface.
  vertex_col_name : string
      The column name that contains the values to be used as vertex IDs.
  type_name : string
      The name to be assigned to the type of property being added. For
      example, if dataframe contains data about users, type_name might be
      "users". If not specified, the type of properties will be added as
      the empty string, "".
  property_columns : list of strings
      List of column names in dataframe to be added as properties. All
      other columns in dataframe will be ignored. If not specified, all
      columns in dataframe are added.
  
  Returns
  -------
  None
  
  Examples
  --------
  >>>

      self,
      dataframe,
      vertex_col_name,
