When a potential subject is trying to access an experiment page but is not
yet logged in, we must first redirect them to the login page.
If they would like to proceed they will then either log in, or else if they
do not already have an account, or forgotten their password, they will find
their way to the signup sheet or to the forgot-my-password page, take care
of business there and then log in.
After all that, we redirect them to the page that they were trying to
reach initially.
