[svn-r1277] Added additional checks into the dataspace code to determine if the hyperslabs
being written out are contiguous in memory and on disk and write/read them as
one I/O operation (if the datatypes don't require conversion). This should be
a good performance boost for those situations. It's especially needed on the
ASCI Red (TFlops) machine. - QAK (from Albert's account on modi4 :-)
