/** Special interface for windows designated to be uniquely created, such as edit windows.
 * The method for creating / using these windows is with UniqueWindowFactory. An example of the usage is:
 * <code>UniqueWindowType window = (UniqueWindowType)UniqueWindowFactory.getInstance().getUniqueWindow(new UniqueWindowType(), specialobject);</code> 
 * A good method to make a unique ID is:
 *<code>String id = getClass().getName() + ":" + <i>(unique data attributes)</i>;</code>*/
