Parameters
[in]mesgIdentifying messages
[in]hiA horizontal index type
[in]arrayuThe u-component array to be checksummed
[in]arrayvThe v-component array to be checksummed
[in]haloshiftThe width of halos to check (default 0)
[in]symmetricIf true, do the checksums on the full symmetric computational domain.
[in]omit_cornersIf true, avoid checking diagonal shifts
[in]scaleA scaling factor for these arrays.
[in]logunitIO unit for checksum logging
[in]scalar_pairIf true, then the arrays describe a a scalar, rather than vector
