I am trying to return type "Creative" from the "get" endpoint. I am getting the 
follow stack trace, and my code is below:

Starting work on this over the weekend. Sorry the late start...

As a work around, have your model as a package library, then install it into 
go-path and then import it as a full reference... not relative reference.

In case anyone else checks this bug out; you will get an almost identical stack 
trace if you forget to specify the 'consumes' and 'produces' attributes inside 
the RestService annotation..

I now appear to be getting this same error.  I do not have a relative import 
nor am I missing consumes and products from my Service struct.

I added a comment to my other issue.  #9
