This shows how to page thru a resultset in a simple manner. It produces a set of links where-ever its called that looks like:
[ 1 2 3 4 5 6 7 ]
and so on. For extremely large resultsets, this function may not be aproppriate as the list of links could get very long, though you can mitigate that by using a larger display amount value, which is the number of items to show on any one page.
