GUI stuff
Slight GUI Changes - Read description for TODO

TODO:
- Change gradient color on KPI tab
- Change gradient color on Intelligence buttons (Yellow, Blue, Green?)
- KPIs 2-4 mimic format of KPI 1
- Make the results of the sustainable and HR (HR KPI1) have some
meaning. For example, for HR 1, "The Feedback score for Sam is 6."
- Whatever else you can think of?
