Convert the Ruby data structure data into tree model data for Gtk and returns the whole model. If the
parameter model wasn’t given a new Gtk::TreeStore is created as
the model. The parent parameter specifies the parent node (iter,
Gtk:TreeIter instance) to which the data is appended, alternativeley the
result of the yielded block is used as iter.
