class_docstr: This is the base interface class for description API classes which provide
  OPF configuration parameters.
  
  This mechanism abstracts description API from the specific description objects
  created by the individual users.
  
  TODO: logging interface?
  
  :param modelConfig: (dict)
      Holds user-defined settings for model creation.  See OPF
      `here <description-template.html>`_ for config dict documentation.
  
  :param control: (dict)
      How the model is to be run. The schema of this dictionary depends on the
      'environment' parameter, which specifies the context in which the model is
      being run.
docstr: :returns: the model creation parameters based on the settings in the config
            dictionary.
