We're working on making a pure swift container image build system that leverages containerization. This PR represents our initial design and initial work towards this goal. The native builder is still in active development and most of the implementation has not been started or completed. We will be opening a series of issues that represent various (but not necessarily all) pieces of work that need to be done here. There are docs included in this PR that describe the overall design of each component and outline some of our goals. The easiest way to view the docs by themselves (since this is a massive PR) is to look at the docs commit in the `Commits` tab. We'd love any feedback! @wlan0 --------- Signed-off-by: Kathryn Baldauf <k_baldauf@apple.com>
