## box-intersect-p

Arguments: box1 box2

Returns true if the argument boxes intersect and returns `nil` if they do not intersect. Boxes which touch just on their edges or at the vertices are not considered to intersect. Thus,

    (make-box 10 10 20 20)

does not intersect

    (make-box 20 20 30 30)

but does intersect

    (make-box 19 19 30 30)

See the description of the `box` class for general information on boxes.
