* @title: GdaTreeManager
* @stability: Stable
* @see_also:
*
* A #GdaTreeManager object is responsible for creating nodes in the tree(s) for which it
* operates.
*
* When creating nodes, a #GdaTreeManager object can (depending on its implementation), get some
* named attributes from the node below which it has to create nodes, using the gda_tree_node_fetch_attribute()
* or gda_tree_node_get_node_attribute(). For example the #GdaTreeMgrColumns manager (which creates a node for each column
* of a table) needs the table name and the schema in which the table is; both can be specified using an
* object's property, or, if not specified that way, are fetched as attributes.
*
* The #GdaTreeManager itself is an abstract type (which can't be instantiated). Use an existing sub class or subclass
* it yourself.
