Create Specs for User Registration Servlet

Hema- here are the specs for the Registration servlet. Let me know if you will be taking in any information other than email/username and password, but I believe that is all Austin is setting in the User DataBase. Please send me an email when you get the UI done and posted and I will get my Servlet tested against it. Also, Please make sure to put in your post method and action to /RegistrationServlet
