ICS3U1 Unit 2 Activity 4: Question 1

// Date: July 21, 2017
// Purpose: To play the game Rock-Paper-Scissors

// This line makes the button, btnPlay wait for a mouse click
// When the button is clicked, the determineEligibility function is called
btnPlay.addEventListener(MouseEvent.CLICK, playGame);

// This line makes the button, btnNewGame wait for a mouse click
// When the button is clicked, the newGame function is called
btnNewGame.addEventListener(MouseEvent.CLICK, newGame);
