"""Collect details of new account, and allow changes on existing accounts.

NOTE: THIS CODE ASSUMES that it is in the PythonTeach realm or outside any
realm requiring authentication. The latter location is used to enter new
details. It doesn't make sense to use this for other realms unless they use
the same authentication base as PythonTeach, since we are handling user data!
