Procedure that computes the total number of elements in the interval. This is equivalent to taking the lengths along each dimension and multiplying them.

 
(import (generalized-arrays intervals)
        (test))

(test "Length of [(0, 0) (2, 2)) is 4"
       4
       (make-default-interval (vector 2 2)))

(test "Length of [(1, 1) (3, 4)) is 6"
       6
       (make-interval (vector 1 1)
                      (vector 3 4)))
