Concept is to stash store a entry_ids of playa entries to pass to jquery-nivoslider call, so that both the slider div and the call will not have identical slider ID's resulting with conflict.
As of now, when using process="end" tag, it doesn't appear to have playa parsing the vars in the proper order.
