• Add ALLOYUI stuff to your host page, not added automatically as in e.g. Liferay they most likely already exist. Example of that using @JavaScript/@Stylesheet annotations
• Otherwise, use like any other Vaadin Add-on component

• Initial POC

• Smarter JSON state deserialization, could use references in Transition class instead of names
