 * Function : KINBand
 * -----------------------------------------------------------------
 * A call to the KINBand function links the main solver with the 
 * KINBAND linear solver. Its arguments are as follows:
 *
 * kinmem - pointer to the integrator memory returned by KINCreate.
 *
 * N      - problem size
 *
 * mupper - upper bandwidth of the band Jacobian
 *
 * mlower - lower bandwidth of the band Jacobian
 *
 * The return value of KINBand is one of:
 *    KINDLS_SUCCESS   if successful
 *    KINDLS_MEM_NULL  if the kinsol memory was NULL
 *    KINDLS_MEM_FAIL  if there was a memory allocation failure
 *    KINDLS_ILL_INPUT if a required vector operation is missing
 *                        or if a bandwidth has an illegal value.
