Hello - is this still in progress?

We require the lift of an association rule for a production use case. We can solve it for
our own end, but it would be more elegant to build the lift method into the AssociationRules
class, and it feels like that should be fairly trivial. Surprising that it's been unresolved
for 2.5 years, but, understandable.

If a pull request is still necessary, I'll be happy to figure it out.

We require the lift of an association rule for a production use case. We can solve it for

it's been unresolved for 2.5 years.
