added a filter to check if user is logged in, currently it intercepts calls to /mybootstrap only. Added an image to jumbotron and index is now the main page. Also added a logout servlet so that it destroys the current session of the user. You can go from index to my bootstrap by pressing Link at the nav-bar. Next i will configure the nav bar a little more and will create the database conn to insert a new estate from user profile(submitListing)
