class_docstr: This is a wrapper class of luigi.Task.
  
  The key methods of a TaskOnKart are:
  
  * :py:meth:`make_target` - this makes output target with a relative file path.
  * :py:meth:`make_model_target` - this makes output target for models which generate multiple files to save.
  * :py:meth:`load` - this loads input files of this task.
  * :py:meth:`dump` - this save a object as output of this task.
