[rules-users] Firing only changed object rules in stateful sessions

[Mauricio Salatino]

Hi,
Rules reacts on facts changes, if you have one big fact the changes inside
them will not fire reactions until you update your big fact, that cause that
all the rules over that big fact fires again.
To solve this, you can add control properties to your fact and to your
rules.
