           1) Mail address (should not be empty and should be an email address)

           3) A Password field (should not be empty)

           Display a warning message if the Form is invalid AND was touched. Display a warning message below each input if it's invalid.

           Upon submitting the form, you should simply print the Value of the Form to the Console.
           Optionally, display it in your template.
