+
+        This is most easily depicted as a set of integers, bounded by
+        a lower and an upper value - but excluding the upper
+        value. All inbetween values are included in the set (see also
+        http://en.wikipedia.org/wiki/Interval_%28mathematics%29).
+
+        The set is half-open, i.e. the lower bound is included, the
+        upper bound not (if you're used to the notation - we're
+        talking about [a,b) here, compared to closed [a,b] or fully
+        open intervals (a,b)).
+
+        If you don't need a half-open interval, check B1IRange.
+
+        That means, isInside(val) will return true also for values of
+        val=a, but not for val=b.
