Initial commit
***************Changes to the login controller*****************************
Login controller no longer needs a validate credentials function, instead it uses the default index function to validate the login form. Login controller now serves as a default redirect in case user is not logged in. This redirect is made at the constructor of every controller as opposed to the earlier implementation of a function that checked for this and loaded the login view.This was done because the controller would continue to load other views along with the login view, despite the failed check. Thus a redirect was preferred  and the login controller was modified accordingly.

*******Changes to aside view*********************
the correct view is now displayed when user is not logged in

*******Changes to all controllers****************
code to prevent direct access added. a redirect to login controller in case the session was not set.
Fixed the back button after logout issue.
