The documentation
http://gtkmm.sourceforge.net/gtkmm2/reference/html/classGtk_1_1TreeView.html
#a27
suggests there is a function TreeView::remove_all_columns, but I can't see
that in the source code. (gtkmm-1.3.18)

It seems like a useful function - should it be there?  Alternatively I guess
one could repeatedly call TreeView::remove_column.
