changed seletion code. SOP now knows about parts selection. UI actions are sent to SOP and this reports to SOG. Group is selected if any part is selected.sop.isSelect get() is only used in SOG. Will need to be improved for better performance on largelinksets. *UNTESTED* NEEDS CHECKING for side efects
