This column wraps another column so that when that delegate column renders, it is
given a JobWrapper that provides a filtered list of Runs to the column.
TODO bug - deleting a view doesn't work - for now, this view just doesn't do any filtering
TODO bug - renaming a view only works some of the time because if this filter isn't used between
the time the view was renamed and a save takes place, this filter won't know about
the rename.
