v2.1

Regarding to Admin Scenario, I have added a necessary constraint which
is preventing user update a duplicated value when a user is performing
updating a single Admin. The above action is taken in file named as
editSingleAdmin.php.
About Faculty scenario, this system has partially performed adding a new
faculty, managing all faculties at a glance, and editing a single
faculty.
Thoughts: We still need a 404 page, 505 page, logout page etc. We still
need changing password page, profile page, Project Scenario, and login
page.
Thanks.
