Lessons to be written: Examples module lessons

As of Learn Drupal 7.x-1.0-alpha4, Examples module is included with the Learn Drupal distro. It would probably be relatively easy to create some really great advanced-level lessons to accompany the example modules in Examples. A huge amount of the work of thinking through and documenting the examples is already done here.

To help with these lessons, it may be useful to create a new module in Learn Drupal as a scratch pad. With a simple: scratch.info and scratch.module that has nothing in it. Then lessons can instruct users to through code into scratch.module as they follow along in the lessons.
