*
* Every node in a #GdaTree tree is represented by a single #GdaTreeNode object. There is no distinction
* between nodes which have children and those which don't (leaf nodes).
*
* The #GdaTreeNode is very basic as it only has a "name" attribute: users are encouraged to subclass it to
* add more features if needed (and make use of them by defining a #GdaTreeManagerNodeFunc function and
* calling gda_tree_manager_set_node_create_func()).
