Support structures that exist in multiple files

[hippiehunter]

an initial idea on this is to have a separate template to generate derived classes. Then inside the edm builder we will have to include these derived type along with key and relation information. This can be stored in the HC customization file.

I believe I am running into this same situation - trying to expose multiple files with the same underlying structure. The build fails and I can see that the code generation duplicates method/property definitions. Thoughts/Suggestions?
