> We are getting out of memory errors during import if the number of records to import
is less than 0.5*splitSize (and is nonterminating decimal).
> For example, if the numSplits = 3, minVal = 100, maxVal = 101 then in BigDecimalSplitter.split()
an extraordinary number of tiny values will be added to the splits List and run out of memory
eventually.
> I also noticed that there are no tests for BigDecimalSplitter.
