[windup-dev] Simplifying reports - WindupVertexFrame#gremlin(...), Freemarker ...?framed(SomeModel)

[Jess Sightler]

I would think that this would increase the complexity of the templates 
quite a bit. In general I'm not that fond of this type of thing as the 
templates are harder to test than service and method classes.

How hard would it be to implement?
