Now uses connect-redis.  Not entangling the sessions.
Clearer picture of what's happening.
Only missing the encryption now.
Working.
Example works with both connect-redis and sockets.
Update README.md
Added hint about cross-origin cookies.  Also removed data.sessionStore.
New load/save session code.
Removed experiment.
Eliminated stub arguments.
Sessions work for sockets again, using the new strategy.
Cleanup.
Added deprecation warning and default io MQ adapter store to config.
Redis MQ stuff patched up.
Cleaned up redis session stuff.
Refactored to allow for forced req.session.save() usage at user level code.  Actually makes it cleaner as well.
Session secret is always the same.  This has to change, obviously.
Disabled default secret-- this will need to be replaced by a nice warning and an automatic generation when new project boilerplate is created.
todo stub in REPL
Added default session and io config to boilerplates.  Especially the part about a session secret, which is required now.
