A selection handle policy for placing handles at the two ends of a ConnectionEditPart. All ConnectionEditParts should have one of these, even if the ends of the connection aren't draggable, because this is the primary SelectionEditPolicy for showing focus.
A connection can receive focus but not selection by pressing Control+/
on
the keyboard.
