[AJAX] 

Continue to enhance the CSNS Mailing List you developed in Homework 4 by adding two AJAX user interface controls. Note that you may use any AJAX library of your choice.

1. (15pt) When a user clicks on the Subscribe (or Unsubscribe) button (or the equivalent in your user interface), an XmlHttpRequest is sent to the server, and if the request is successful, the button is changed to Unsubscribe (or Subscribe) without refreshing the whole page.
