Document a good user experience for gathering a county #448

1. Do people in your state know what county they live in? If so, you could offer a drop down menu.
2. If they don't, you can use the .normalized_address() method on the address to get the county
3. If the .normalized_address() doesn't return a valid county name in your state, you can offer a drop-down menu.

Document how to handle this:

1. In a question
2. In the interview order block
3. In the attachment for a DOCX or the attachment block for a PDF
