class_docstr: An interface to incrementally build an SFrame (row by row). It has some
  basic features such as appending multiple rows at once, polling the last N
  rows appended, and a primitive parallel insert interface.
  
  Once closed, the SFrame cannot be "reopened" using this interface.
  
  Parameters
  ----------
  column_types : list[type]
      The column types of the result SFrame. Types must be of the python
      types that are supported by SFrame (int, float, str, array.array, list,
      dict, datetime.datetime, image). Column types are strictly enforced
      while appending.
  
  column_names : list[str], optional
      Column names of the result SFrame. If given, length of the list must
      equal the length of `column_types`. If not given, names are generated.
  
  num_segments : int, optional
      Number of segments that can be written in parallel.
  
  history_size : int, optional
      The number of rows to be cached as history. Caches the last
      `history_size` rows added with `append` or `append_multiple`.
  
  Returns
  -------
  out : SFrameBuilder
  
  Examples
  --------
  >>> from turicreate import SFrameBuilder
  
  >>> sb = SFrameBuilder([int,float,str])
  
  >>> sb.append([1,1.0,"1"])
  
  >>> sb.append_multiple([[2,2.0,"2"],[3,3.0,"3"]])
  
  >>> new_sf = sb.close(); new_sf
  Columns:
          X1      int
          X2      float
          X3      str
