I get that, and forgive me for being dense, but I don't get how to make it so that my class is created by Guice so that my injections will work.
I see that the application provides a module that's called on startup. Within that module I see a series of functions that call binder.bind and in all of those classes I see that injection works. Looking at that, I would think that I could binder.bind my own class but that doesn't seem to work. I could have syntax issues, but my sense is that there's a fundamental thing that I'm missing.
