+ This methods traverses up the hirarchy to find out if this Type is located
+ inside a Class or Widget Class. It then return the name of that class. If
+ need_nest is set, class_name searches all the way up the tree and concatenates
+ the names of classes within classes, separated by a "::".
+
+ \param need_nest if clear, search up one level to the first enclosing class.
+ If set, recurse all the way up to the top node.
+ \return the name of the enclosing class, or names of the enclosing classes
+ in a static buffe (don't call free), or NULL if this Type is not inside a class
