For my first plug-in, I want to add a context action for interfaces that creates a proxy using a StringTemplate file. I munge the interface definition a bit and feed it into the StringTemplate instance and get a blob of text back. I think I've figured out how to create the context actions, but whats the best way to stuff this into the file after the interface definition? Is there a "raw text" element that can be added? Do I need to get the editor instance and paste it in?
