At the beginning of the semester, the teacher will perform a setup process, involving the following steps:

• Create a Google Sheet gradebook document (noting the gradebook_document_id from the URL), and a specific sheet in that document to designate as the current gradebook (specifying a gradebook_sheet_name).
• Create a Google Form and corresponding Google Sheet of responses, for Weekly Check-ins (noting the checkin_document_id and sheet name (which by default is "Form Responses 1").
• Designate a title for the course (i.e. "TECH 9999 (Summer 2040)")
• Designate a unique identifier for the course (i.e. "tech-9999-summer-2040")
• Designate the email addresses of zero or more TAs who will have access to view certain privileged information in the system.
• Designate the "active term" start and end dates (so we know which courses are currently "active")

The teacher should be able to input this information into the system via web form, perhaps on a page like /courses/new (and corresponding update form at /courses/<course_id>/update). Perhaps the system creates the google sheet document(s) automatically, based on the course title and other information input via web form.

After setting up the course, the teacher should be able to view the course page (at /courses/<course_id> like "/courses/tech-9999-summer-2040"). On the Course Page, the teacher should see all the information about the course provided via setup. And there should be a link to the course's roster page (/courses/<course_id>/roster), which reads from the google sheet roster and displays a table of student names and email addresses.
