// TO DO:
// 1. make app run on a schdule, a few times a day, exept when servers are closed.
// 2. communiate availability result to user, screen shot / mapped data of each test center and wether they have slots available

// EXTRA FEATURE: if slot is available, make the bot book the next available slot for you. At present you ould have to login-in yourself ASAP and hope the slot is still available.
