AEGP Support

[mobile-bungalow]

The library is already capable of creating an AEGP. It would be nice to have examples and a convenience macro similar to the one we have for normal effect plugins. AEGP's would also be much more useful if we wrapped the register suite. I have a scrappy example of wrapping the register suite here to create a main-thread idle function in a way that preserves some semblance of type safety.

I would be happy to contribute to the register suite wrapping as well as the boilerplate macro . I'm placing this here as a tracking issue in case anyone has architectural opinions about this fairly large addition.
