ceph-rust 0.1.4

Ceph-rust is a rust-lang specific interface to Ceph librados. You can create a Ceph development environment with the Chef automation tools I created from the following: https://github.com/bloomberg/chef-bcs. It uses the ceph-chef cookbook I created and manage at github.com/ceph/ceph-chef. It will build out a full Ceph environment which you can then use for development etc. See README.md for details.
