Rails engine?

[jonathandean]

Having a generator option alone makes it hard to take advantage of future updates without squashing any changes you may have made to the generated files in the meantime. A Rails engine pattern could help give this and still allow for a generator for non-Rails apps. It would also mean that we could set up a dummy app for CI to actually run the bundled tests.

Another option or baby step could be to vendor the generated files to discourage changes being made to them directly.
