I want to display the contents of an NSArray and WORepetition is

It seems I can do this at least two ways:
(1) ... filter the original NSArray through the computation to make
a new NSArray and use that.
(2) ... play games with the processing of the WORepetition so it
skips items.
Or (2), use a WOConditional within the repetition to do the filtering
for you. This is sort of 'playing games', but unfortunately it's
easy rather than hard.
