> The current implementation of Association rule does not return the frequency of appearance
of each rule. This piece of information is essential for implementing functional dependency
on top of the AR. In order to return the frequency (support) of each rule,   freqUnion: Double,
and  freqAntecedent: Double should be:  val freqUnion: Double, val freqAntecedent: Double
