Fixed bug where every time the schedule and roster views would appear, they would load the data again. This means if you clicked on a player and went back to the roster, the roster would re-load. I implemented two BOOL values to keep track of when the data changes. When a school is selected, both BOOL values are set to YES. The data is only loaded when these values are YES for the respected view. Once the data has been loaded on that view, the respected BOOL value is set to NO.
