A Boundary is a function which takes a Point and determines if it is inside some area. If the Point is outside the area, it returns Nothing. Otherwise, it returns the distance to the edge of the area. Any such Boundary need not be a simple, traditional geometric shape. Though, it is often difficult to calculate the distance for more exotic shapes.
