Publish crates to crates.io

[cdata]

At this time, none of our crates are published to crates.io. This doesn't prevent folks from kicking the tires - one can always include the crates as a git dependency in Cargo.toml. But crates.io doesn't currently support namespacing, and the longer we wait to publish, the more likely it is that someone will squat on our names. So, we should get our crates published ASAP.
