The game is functional now. Added copious comments, as well as reporting the player's score at the end. However, it's not randomly choosing the questions from the list. I'll have to figure out why it's not behaving correctly in that respect. Otherwise, the game works. I would also like to add input sanitization, so that when the player responds, it will only accept 'a,b,c,d' as the answer and reject anything else until the correct input is received.
