By setting a sort function on the box, one can dynamically reorder the children of the box, based on the contents of the children.
The sort_func will be called for each child after the call, and will continue to be called each time a child changes (via gtk.flow_box_child.FlowBoxChild.changed) and when gtk.flow_box.FlowBox.invalidateSort is called.
Note that using a sort function is incompatible with using a model (see gtk.flow_box.FlowBox.bindModel).
