/*Create the Answers list of AnswerCards, which the listview binds to. Generates four AnswerCards, with a Card and Correct properties, indicating if
* this is the right answer. Each loop checks if the random card from the full list of cards of the deck is the correct choice, from the randomly
* chosen card in the hand shown in the carousel view (The GetHand method is generalized so each game can use it, making it a little harder to
* then also generate AnswerCards). Then that card is removed from Cards so there are no duplicates (This means we have to call the DB for a full
* list of cards each time..). Then finally, checks to see if the actual answer has been one of the randomly selected, if not it adds it in a random
* Position. Maybe it would be better to add the actual answer first, but it needs to be in a random position, so the Answers list needs to be populated
* before that.*/
