If box was already bound to a model, that previous binding is
destroyed.
The contents of box are cleared and then filled with widgets that
represent items from model. box is updated whenever model changes.
If model is null, box is left empty.
It is undefined to add or remove widgets directly (for example, with
gtk.flow_box.FlowBox.insert) while box is bound to a model.
Note that using a model is incompatible with the filtering and sorting
functionality in gtk.flow_box.FlowBox. When using a model, filtering and sorting
should be implemented by the model.
