 The sum of the demands of the intervals at each interval point cannot exceed
 a capacity. Note that intervals are interpreted as [start, end) and as
 such intervals like [2,3) and [3,4) do not overlap for the point of view of
 this constraint. Moreover, intervals of size zero are ignored.

 All demands must not contain any negative value in their domains. This is
 checked at validation. The capacity can currently contains negative values,
 but it will be propagated to >= 0 right away.
