* Added user guide sections on Shamir sharing and fault recovery.
* Reorganized SocketCommunicator statistics, and added statistics organized by message type.
* Added the cicada-perf command for benchmarking communications.
* Added `indices` and `threshold` properties to ShamirBasicProtocol and ShamirProtocol.
* SocketCommunicator setup didn't always use the correct rank and name in log output.
* Fixed a problem with the way thresholds are constrained in ShamirProtocol.
* Explicitly specify process names for debugging with SocketCommunicator.run().
* Removed obsolete code.

0.5.1

* A botched merge left some changes out of the 0.5.0 release.

0.5.0

* ShamirProtocol provides the same operations as AdditiveProtocol.
* New ShamirBasicProtocol provides a subset of operations, but with relaxed constraints on share degree.
