* @brief The StyleDialog class

* add and delete selectors. Elements can be added to and removed from the selectors
* in the dialog. Selection of any selector row selects the matching objects in
* the drawing and vice-versa. (Only simple selectors supported for now.)
*
* This class must keep two things in sync:
* 1. The text node of the style element.
* 2. The Gtk::TreeModel.
