   9  * n is the number of scheduling dimensions within the band.
  10  * coincident is an array of length n, indicating whether a scheduling dimension
  11  *      satisfies the coincidence constraints in the sense that
  12  *      the corresponding dependence distances are zero.
  13  * permutable is set if the band is permutable.
  14  * mupa is the partial schedule corresponding to this band.  The dimension
  15  *      of mupa is equal to n.
