  File: BorderLayoutFrame.java
  Purpose: BorderLayoutFrame.java  - BorderLayoutFrame is the code for the GUI, sets up Screen in connstructor, sets up question array and
                                     game is primarily contained in the button action listener
  Compiler/IDE: OpenJDK 1.8.0_151 (compiled from CLI) - Atom / Vim text editors
  Operating system: Debian Stretch 9
  Reference(s): https://docs.oracle.com/javase/tutorial/uiswing/layout/grid.html - GridLayout
                https://docs.oracle.com/javase/tutorial/uiswing/events/actionlistener.html - Action listener
  Extra Note: Don't question why it's called BorderLayoutFrame when I'm using grid layout.. I startd with BorderLayout.. got frustrated and
              Switched to GridLayout and never bothered to change it (it_just_works.java)
