[Esteban Aliverti]

As far as I know, these 2 functions already exist in 5.1.1. Don't they?

> I'll stick to a custom accumulate function since it is more consice than
> the init/action/result approach.
> And since I am using Drools 5.1.1, I'll create functions named collectList
> and collectSet to be "future proof" :-)
