9/* Information about a band within a schedule.
10 *
11 * n is the number of scheduling dimensions within the band.
12 * zero is an array of length n, indicating whether a scheduling dimension
13 *	results in zero dependence distances for the proximity dependences.
14 * pma is the partial schedule corresponding to this band.
15 * schedule is the schedule that contains this band.
16 * parent is the parent of this band (or NULL if the band is a root).
17 * children are the children of this band (or NULL if the band is a leaf).
18 *
19 * To avoid circular dependences in the reference counting,
20 * the schedule and parent pointers are not reference counted.
21 * isl_band_copy increments the reference count of schedule to ensure
22 * that outside references to the band keep the schedule alive.
