To run a session similar to those on 

http://www.thumbtack.com/challenges, simply ruin Main.py

Note that this uses a deferred writer, so that responses to 

commands are suppressed until you send "END" at which point,

the entire output is written to screen.

Example session:

SET a 50

BEGIN

GET a

SET a 60

BEGIN

UNSET a

GET a

ROLLBACK

GET a

COMMIT

GET a

END

50

NULL

60

60

Note that there is no prompt symbol (as in the sample input/output),

but one can be specified when creating the DatabaseManager.

The following DatabaseManager:

DBM = DatabaseManager.DatabaseManager(GENERIC_DB, '>>> ')

produces the following session (same as above)

>>> SET a 50

>>> BEGIN

>>> GET a

50

>>> SET a 60

>>> BEGIN

>>> UNSET a

>>> GET a

NULL

>>> ROLLBACK

>>> GET a

60

>>> COMMIT

>>> GET a

60

>>> END
