David Li / @lidavidm:
@sunchao, I have some basic implementations. Printing nested arrays is difficult; I've punted on that for StructArray/ListArray. Really, we need Array to have a Debug trait bound as well - is that acceptable?

In the future, we may also want a pretty-printer API to make nested arrays look better (with indentation, etc).
