ARKBand:
A call to the ARKBand function links the main ARKODE integrator
with the ARKBAND linear solver.
arkode_mem is the pointer to the integrator memory returned by
ARKodeCreate.
N is the size of the ODE system.
mupper is the upper bandwidth of the band Jacobian
approximation.
mlower is the lower bandwidth of the band Jacobian
approximation.
The return value of ARKBand is one of:
ARKDLS_SUCCESS if successful
ARKDLS_MEM_NULL if the arkode memory was NULL
ARKDLS_MEM_FAIL if there was a memory allocation failure
ARKDLS_ILL_INPUT if a required vector operation is missing or
if a bandwidth has an illegal value.
