Brandon ref5 stepback

This creates a workable GWT Ref<?> serialization. I get a domain object with Ref<?> object. 

I haven't tested saving an object from client yet. 

I think the best way to create gwt project for testing. My next step is to create a ObjectifyGwtTesting maven project where the parent could be objectify module. This way no jars would have to be compiled for testing the ObjectifyGwtTesting project. The gradle setup is a pain for me b/c I don't know it yet. But both maven and gradle environments could exist together if you did want to merge what I did make in the future. I'm not sure what you would be copsetic with at this point. From my point of view once you get  past a maven pom.xml setup, the lifecycle is a much easier to deal with from IDE development setup to releasing to sonatype. Anyway, thats my point of view. :)

In either case, I need to setup a sandbox gwt module for building some test cases and be sure I have what I wrote working fully. This would allow for testing the serializers and serialization patterns. But I'm tired and I'm going to pull at this stage for preview what I've done so far.
