Update EventEmitter tests to test against node interface
Upgrade base64
Update streams2 example to use compliant event-emitter interface
Start StateToContent Transform
state-to-content is not a transform
StateToContent works in ArchiveStateStream. It now emits Content
Rename archive-state-stream to collection-archive
StreamManagers work with streams2 and writable views. livefyre-helper creates a CollectionArchive for its reverse stream
Add test for adding a streams2 stream to a streamManager after the streamManager is started
streams2 in stream-managers only read out their initial buffer of content. Calling StreamManager.start() causes CollectionArchive to read more data
Merge branch 'stream' of github.com:Livefyre/streamhub-sdk into stream
