[rules-users] Accumulate / collect

[Bruno Freudensprung]

Hi Wolfgang, hi Estaban,

Many thanks for your insights!
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" :-)

Best regards,

Bruno.
