 //@PURPOSE: Defines a data model for tree views, containing the
 // elements of all namespaces.
 //
 //@CLASSES:
 //  lvtmdl::PackageTreeModel:
 //
 //@DESCRIPTION: This component prepares the data of a
 // namespace to be displayed on a tree view
 //
 /// Usage:
 ///------
 ///  Create a model and pass the Dbo::Session to it,
 ///  then plug the model onto a view.
 ///
 ///  You should manually connect to expand and collapse
 ///  from the treeview Expanded() and Collapsed() signals
 ///  as we need that information to fetch the data from
 ///  the namespaces.
