Possible to use phobos.js as express/connect middleware?

I have an existing Express application, and I'd like to try using Phobos to implement a new API in it (e.g. mount it to `/new-api/v1/*` with `app.use` or by passing my `app` object & path to it, etc.). Is this possible/supported? The example I saw ("Getting Started" / bootstrapping) instead required having phobos be responsible for creating the Express app, which is not what I want.
