docstr: Returns a structured description of the model, including (where relevant)
  the schema of the training data, description of the training data,
  training statistics, and model hyperparameters.
  
  Returns
  -------
  sections : list (of list of tuples)
      A list of summary sections.
        Each section is a list.
          Each item in a section list is a tuple of the form:
            ('<label>','<field>')
  section_titles: list
      A list of section titles.
        The order matches that of the 'sections' object.
