Super-simple tool for administering coding quizzes, and an excuse to play around with the Flask/Postgres/SQLAlchemy stack on Heroku.

Motivation: I have had good experiences using a service like Codility to administrate interview pre-screen coding problems, but I wanted to be able to write my own tests and specifically do not want auto-grading or a hard time limit -- I care about time-limits only insofar as I don't want to give people so much time that they can outsource their solution to StackOverflow...but if a candidate takes 2:05 instead of 2:00, who cares?
