* About: This class handles the 'Play' screen.
* It has an action bar at the top of the screen displaying a timer and number of errors the user has made. 
* It has 50 buttons which display the number sequence on the screen. When a button has been correctly pressed, it becomes unpressable 
* and becomes translucent. After all buttons have been correctly pressed, it will determine if the final time was good enough to be a 
* high score and update the saved high scores accordingly.
