/* 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.
