*This is the Crosshair class, which represents the point on screen at which the user is aiming. It is a simple class, with only one variable; its position on screen,
*and methods to access and change said. The setCentre method is only called by the MouseMotionListener in the A3JPanel class, which moves the crosshair to where the
*cursor is located on screen. It also contains the details used to draw a simple crosshair to the screen.
