- interval-contains-multi-index? interval index-0 index-1 ...procedure
If interval is an interval with dimension $d$ and index-0, index-1, ..., is a multi-index of length $d$, then interval-contains-multi-index? returns #t if
(interval-lower-bound interval j) $\leq$ index-j $<$ (interval-upper-bound interval j)
for $0\leq j < d$, and #f otherwise.
It is an error to call interval-contains-multi-index? if interval and index-0,..., do not satisfy this condition.
