The sheet for registering new students

Answers the sheet a teacher fills in to register new students: its columns in order, each with its header, the register_students argument it fills, whether it is required, its format and an example; two invented example rows; the rules; and how many rows one call takes. Nothing is read from the platform and it takes no olympiad. Offer it when a teacher asks for a template, a blank sheet or which columns to use, write it out for them as a CSV or a spreadsheet with exactly these headers, and leave the example rows out of anything that is sent.
