Detailed Description
A two-dimensional interval over integers.
This is a set of real numbers, bounded by a lower and an upper pair. All inbetween values are included in the set (see also http://en.wikipedia.org/wiki/Interval_%28mathematics%29).
Probably you rather want B2IBox for integers.
The set is closed, i.e. the upper and the lower bound are included (if you're used to the notation - we're talking about [a,b] here, compared to half-open [a,b) or open intervals (a,b)).
That means, isInside(val) will return true also for values of val=a or val=b.
