Finding duplicates in a list

Hi Ian,

I have a couple ideas... Would you be able to upload a sample list 
somewhere -- the result of ijwAPLIB_getAllChecksums() -- so we could try it 
out and measure? Also, just want to double-check that you intend to produce 
a list of duplicate items, not a list of uniques.
