	class EditorGUITextField extends EditorWindow {

		static function Init() {
			var window = GetWindow(EditorGUITextField);
			window.Show();
		}
		
		function OnGUI() {
			EditorGUI.DropShadowLabel(Rect(0, 0, position.width, 20), 
			"Select the objects to rename.");
			objNames = EditorGUI.TextField(Rect(10,25,position.width - 20, 20),
						"New Names:", 
						objNames);
			if(Selection.activeTransform)
				if(GUI.Button(Rect(0, 50, position.width, 30), "Bulk rename!"))
