M5 - Registration

[ajaydeepsingh]

• [x] Add the registration screen to your app. A new user should be able to register by entering their information (like name, email, and password). If accepted, the new user should be added to the system. If cancelled, the user should not be added.
• [x] During registration, the new user’s account type (User, Admin, or Shelter Employee) should be specified. In a real application, we would have controls for determining this, but for this class project, we will have registration designate accounts as basic Users. You may implement creation of the other two account types for extra credit.
• [x] When registration is working, you may remove the hard-coded user/pass from the app.
