TkDemo Full Implementation
- This version allows the user to pick a file in the directory the user navigates too, and then opens the file, reads its contents, and puts it inside the text area.

Synthetic Email Addresses
- These are not real addresses. Just random first names made into what looks like real email addresses, formatted as CSV.
