Middleware related to transactions and database connections.
At this time it is very basic; but will eventually sprout all that
two-phase commit goodness that I don't need.
.. note::
This is experimental, and will change in the future.

Provides a callable interface for connecting to ADBAPI databases in
a WSGI style (using the environment). More advanced connection
factories might use the REMOTE_USER and/or other environment
variables to make the connection returned depend upon the request.

Provides a simple mechanism for starting a transaction based on the
factory; and for either committing or rolling back the transaction
depending on the result. It checks for the response's current
status code either through the latest call to start_response; or
through a HTTPException's code. If it is a 100, 200, or 300; the
transaction is committed; otherwise it is rolled back.
