Method for importing 'laneSet' element from diagram file.

:param process_attributes: dictionary that holds attribute values of 'process' element, which is parent of
    imported flow node,
:param lane_set_element: XML document element,
:param plane_element: object representing a BPMN XML 'plane' element.
