Add lift (interestness) in rules

[huwangxiong]

Hi,
I want to add lift (lift(X ⇒ Y ) =conf (X ⇒ Y )/supp(Y )) after each rules. In your code, may like lift = getSupport(item)/(getSupport(element)*getSupport(remain)). But an error occured (ValueError: too many values to unpack) when I do so. Can you modified the code and add the lift value in each rules. Many thanks.

Best.
