0.7.0 Release Candidate 0 (Experimental)

This is an experimental release of C and Java native extensions. It merges the ruby-atomic gem into the 0.6.1. It was built using an automated build process that creates pre-compiled binary releases for most major operating systems. We believe this release to be highly stable and highly portable. The C/Java native code we imported was highly battle-tested. Since this is our first release with native extensions we urge cautious experimentation.
