class_docstr: Helper class to create tables for the documentation.
  
  The ``generate`` method creates the table rst file (and possibly any other
  files, such as images, used by the table). This method internally calls
  the ``fetch_data``, ``get_header`` and ``get_row`` methods, which should be
  provided by any subclass.
  Each table is generated from a list of 'row_data' provided by the ``fetch_data``
  method. The ``get_header`` and ``get_row`` methods generate the required rst
  for the table's header and table's rows respectively.
