Admin interface

I set up the structure for the staff interface today. It is divided into four tabs: Dashboard, Loans, Equipment and Settings. Each tab is a separate canvas so we can work on different tabs without worrying about interfering with each other's work.

I set up the loans tab, which allows users to apply different filters to the loans stored in the database and find specific loans. I am going to work on the dashboard tab next. Long is going to set up the settings tab.
