Detailed Description

Scene for displaying the game board.

Created anew at the beginning of each game. Contains the visual representation of the board. Is used to interperet mouse clicks from the user (if the view is unlocked) Contains QGraphicsLineItems for lines, QGraphicsEllipseItems for the dots and QGraphicsRectItem for when a square is complete.
