   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  * map is the partial map 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.
