If interval1 and interval2 are intervals built with

(make-interval lower-bounds1 upper-bounds1)

and

(make-interval lower-bounds2 upper-bounds2)

respectively, then interval= returns

(and (equal? lower-bounds1 lower-bounds2) (equal? upper-bounds1 upper-bounds2))

It is an error to call interval= if interval1 or interval2 do not satisfy this condition.
