> 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
