Releasing

1. Change the version in top level gradle.properties to a non-SNAPSHOT verson.
2. Update the CHANGELOG.md for the impending release.
3. Update the README.md with the new version.
4. git commit -am "Prepare for release X.Y.Z." (where X.Y.Z is the new version)
5. ./gradlew clean uploadArchives.
6. Visit Sonatype Nexus and promote the artifact.
7. git tag -a X.Y.X -m "Version X.Y.Z" (where X.Y.Z is the new version)
8. Update the top level build.gradle to the next SNAPSHOT version.
9. git commit -am "Prepare next development version."
10. git push && git push --tags
11. Update the sample module to point to the newly released version. (May take 2 hours)

If step 5 or 6 fails, drop the Sonatype repo, fix the problem, commit, and start again at step 5.
