Include pages with starter code for Take-Home Assessments?

[hschafer]

It might be good to make pages with specifications and starter code for take-home assessments so those working at home can do them.

Some notes on implementation:

• Maybe add a disclaimer that these are public versions of our assignments and might not align with assignments if they are using this book for a class. Remind them to always default to their instructor's policies and assignments used.
• We should not include test runners here since we likely don't want to give away the tests for take-home assessments.
• Would probably make sense to put as a new page inside the appropriate module's directory.
