Moved Server into Log package; replaced ServerId with Name, from courier; removed methods from RaftLog. Added documentation on Log methods.
Whoops: fixup for accessor serverId -> serverName
Renamed newRaft -> mkRaft
Moved logs back to using Index, not LogTime, for appending / fetching / committing entries. Some cluster failures, but enough successful runs to continue.
Merge branch 'master' of github.com:hargettp/raft
