Only the abstract TableSelectionModel is a no-op, the implementations
(one each for TableView and TreeTableView) will both override and
provide the implementation that I already have in the patch for
TableView. I would rather have the implementation in the base class but
this is not feasible due to requirements in looking up column indices.

I haven't included discontinuous selection in this round of performance
research, but in general the changes in the RT-33442 changeset will have
the same drastic improvement there as well. However, as you note, there
is not a full implementation of discontinuous selection implemented in
TableView yet, so the point is a little moot at this stage.
