ticket #140

re-factored the code so that it now looks at all matched records and
adds all unique elements to the options drop-down; thus if the 7th
record has an element that does not exist in any other record it will be
present in the option drop-down.

also re-factored the example record table output so that it will show
duplicate element name values, thus if two or more dc:creator elements
exist, all will be displayed
