> AssociationRules can generate redundant rules such as:
> * (A) => C
> * (A,B) => C  (redundant)
> It should optionally filter out redundant rules.  It'd be nice to have it optional (but maybe defaulting to filtering) so that users could compare the confidences of more general vs. more specific rules.
