Currently, the top-level of openai_agents has all of the samples mashed together as one project at the top level dir. I think it makes the addition of this as a subdir a bit confusing. I wonder if we should move the current sample set into a subdir (e.g. "simple" or something) or make each sample its own dir as we are doing with these newer ones.

EDIT: I now see #221 will fix this, thanks! Can disregard this comment.

I am a little concerned we are adding lots of OpenAI sample code with no tests to confirm it continues to work. Granted I know this is unfortunately OpenAI's approach to samples, but ideally we can have some test somewhere. We have other samples where we have done this and it comes back to bite us hard when people report it stops working and we have to scramble (this is the case with the Sentry sample which has now remained broken for a long time).

(just adding this general comment, deferring code review to Dan/Tim)
