Automatically book 2nd dose vaccine at closest location Ontario

 *        NOTICE: I have been told that the script no longer works and has been blocked.
 *
 *          It is unfortunate that the Ministry and Accenture don't see
 *          this as an opportunity to improve the experience for their users.
 *
 *          I was able to create a better user experience using nothing more than
 *          their own website's code and their own API. When 100 people want the same
 *          1 appointment, and they have to race against each other to click first, and 99%
 *          of those people will not get the appointment, 99% of people will be disappointed.
 *          That might be acceptable for trying to buy rare sneakers, but not for
 *          vaccination and medical care in general.
 *          
 *          Implementing this kind of "match me with my preferences" on the server-side
 *          would allow people to simply 'queue up' while the system tries to match them
 *          with an appointment automatically, and it's clearly already possible with the
 *          infrastructure that is in place.
 *          
 *          If you used the script and it has helped you, consider this experience next
 *          time you think your government or your employer should cut costs on software
 *          and IT.
 *
 *          I am very thankful for everyone who has messaged me their support. The original
 *          script remains below.

 *     You MUST be on this page as pictured: https://i.imgur.com/dfAe1sD.png
 *  3. Fill in your information below. Your location will be used for the distance
 *     calculation. Your personal info will be used to book the appointment.
