If a strike is immediately followed by a second strike, then we can not total the value of first strike until they throw the ball one more time.

 This means the current running total is 48.
 
-The tenth frame in the game is a special case. If someone throws a strike or a spare then they get a fill ball. Fill balls exist to calculate the total of the 10th frame. Scoring a strike or spare on the fill ball does not give the player more fill balls. The total value of the 10th frame is the total number of pins knocked down.

 * `roll(pins : int)` is called each time the player rolls a ball.  The
   argument is the number of pins knocked down.
 * `score() : int` is called only at the very end of the game.  It
