files besides ProgramDb files in a Ghidra project

[djsteffey]

What I would like to do is be able to add other files, like perhaps a text file, to a Ghidra project. After the file is added it will be show in the project window. When the file is double clicked to open it, I will generate a subclass of the IProgram interface and would then like to open it in the CodeBrowser interface.

I have done plugin development for Ghidra so I am familiar with the tool chain and how to do all that. What is confusing is how to do what I am speaking of above. It looks like I will have to extend DomainObjectAdapter to represent the data in the file? Or extend GhidraFile to handle the actual file in the project? There is really no documentation or example code I can find anywhere that will help me with this.
