The same player serves for an entire tennis game. Before each point, the score is announced, server's score first. A game is won when one of the players has at least four points and is at least two points ahead.
In tennis, scores of zero, one, two, and three, are announced as love, fifteen, thirty and forty. Thus, if the score were 3-0, your application should announce, Forty-Love. Use a TextArea to announce the scores as the game progresses, so you can see the entire game.
If the score reaches 3-3, then, until the game is decided, the score is announced as "deuce" for ties and "advantage server" or "advantage receiver", depending on who is ahead by one.
Your program should announce the score before each point, as well as the winner of the game. Once the game is over, it should not allow additional points.
Assume for now that the user will push one of two Buttons for each point, one if the server gets the point, the other if the receiver gets the point.
