Hey There,
Sorry for the late reply - the holiday season is always difficult.
First, I have to recommend that you try upgrading to Forge 2, since it will make doing this infinitely easier. Forge 1 did not really handle extensions very well beyond the simple plugin mechanism. Forge 2 is much simpler and easier to extend, and Forge 1 is no longer under development or maintenance.
You should take a look at the new AngularJS scaffold for Forge 2. The code is still a bit cluttered, sorry, but the concept of extending Forge 2 is far simpler:
Just implement the ScaffoldProvider interface, then install your addon into Forge 2:
Once your addon is installed (see installation instructions on the angularjs addon page - just replace with your addon's coordinates) your scaffold should be listed in the choices for available scaffolding when running the "Scaffold - Generate" / 'scaffold-generate' command.
I hope this is helpful, and sorry again for the late reply.
