//the idea is to only expose the very very lowest level data in the unity api. this data is uncrawled.
//you get the raw heap bytes, you get typedescriptions, and an overview of native objects, and that's it.
//
//the crawler, the higher level "c# idiomy api", and the UI window that uses that api
//we can develop in an opensource github project, and iterate
//on outside of the unity release trains.
