/**
* Compare 2 rows of data using the natural keys and indexes specified.
*
* @param o1
* @param o2
* @return

try {
// First compare on the natural keys...
//
int cmp = rowMeta.compare(o1, o2, keyIndexes);
if (cmp!=0) return cmp;
// Then see if the start of the date range of o2 falls between the start and end of o2
//
ValueMetaInterface fromDateMeta = rowMeta.getValueMeta(fromDateIndex);
ValueMetaInterface toDateMeta = rowMeta.getValueMeta(toDateIndex);
