No -- we don't want arguments here.  But I need to take the PredicateNodes out of the EvaluationLinks.  The arguments are given within the 'sentence-templates' the SV, SVO, SVIO, etc. rules.  The idea is that PLN will combine the results of the how, when, where, why rules with the results of the sentence-templates, as suggested by William.
