S )ÚAxislineStyleaó  
    A container class which defines style classes for AxisArtists.

    An instance of any axisline style class is a callable object,
    whose call signature is ::

       __call__(self, axis_artist, path, transform)

    When called, this should return an `.Artist` with the following methods::

      def set_path(self, path):
          # set the path for axisline.

      def set_line_mutation_scale(self, scale):
          # set the scale

      def draw(self, renderer):
          # draw
