SQLAlchemy integration

I don't know and can't find any info about that.

I ran a little test to see how sessions work. Here's the result: https://gist.github.com/tsukanov/bc5735162e0103eb658b. Not sure how correct it is.

More info about session attributes that I used is available at http://docs.sqlalchemy.org/en/rel_0_9/orm/session.html#session-attributes.
