guiding questions to explore and compare project organizations

to the [project organization episode](https://github.com/brownsarahm/python-data-project/blob/gh-pages/_episodes/02-project-setup.md)

the idea is to start that section off with an activity to explore and discuss organizations before introducing guiding principles.

links txample projects would also help and not only things that are 'good'

Open _episodes/02-project-setup.md and review the project organization section. Add an activity with guiding questions for exploring and comparing organizations, plus links to varied example projects rather than only recommended ones. Done means the activity appears before the guiding principles and supports the stated discussion.
