class_docstr: Base class for all pipeline objects.
  
  Notes
  -----
  This class should not be instantiated, only subclassed.
docstr: Allows retrieving additional run information from the pipeline.
  
  Can be overridden by subclasses to return additional information to
  the optimization algorithm.
