-/**
- * XObject
- * Yet another attempt to create a usable object construction library for seed..
- * 
- * Why is this useful?
- * A) It turns rather messy code into a tree structure, making it easy to find code relating to 
- *    an interface element
- * B) In theory it should be gjs/Seed compatible..
- * C) It provides getElementById style lookups for elements.
- * D) It provides classic OO constructors for Javascript (extend/define)
- * E) It does not modify any buildin prototypes.. 
- *
- * Extend this.. to use it's wonderful features..
- * 
- * normal usage:
- * XObject = imports.XObject.XObject;
- * 
- * Xyz = new XObject({
- *     xtype: Gtk.Window,
- *     id : 'window',
- *     items : [
- *     
- *     ]
- *  });
- *  Xyz.init(); // create and show.
- * 
- * 
- * 
- * @arg xtype {String|Function} constructor or string.
- * @arg id {String}  (optional) id for registry
- * @arg xns {String|Object}   (optional) namespace eg. Gtk or 'Gtk' - used with xtype.
- * @arg items {Array}   (optional) list of child elements which will be constructed.. using XObject
- * @arg listeners {Object}   (optional) map Gobject signals to functions
- * @arg pack {Function|String|Array}   (optional) how this object gets added to it's parent
- * @arg el {Object}   (optional) premade GObject
- * 
- *  --- needs a xdebug option!
- * 
- * 
- * He's some questions.
- * - should we generate ID's for all elements? (if so we probably need to garbage collect)
- * - should we have a special property to use as the constructor / gobject.properties rather
- *   than sending all basic types to this?
- * 
- *
