/* Information about a band within a schedule.
 *
 * n is the number of scheduling dimensions within the band.
 * coincident is an array of length n, indicating whether a scheduling dimension
 *	satisfies the coincidence constraints in the sense that
 *	the corresponding dependence distances are zero.
 * pma is the partial schedule corresponding to this band.
 * schedule is the schedule that contains this band.
 * parent is the parent of this band (or NULL if the band is a root).
 * children are the children of this band (or NULL if the band is a leaf).
 *
 * To avoid circular dependences in the reference counting,
 * the schedule and parent pointers are not reference counted.
 * isl_band_copy increments the reference count of schedule to ensure
 * that outside references to the band keep the schedule alive.
