[rules-users] Indicating "used" rules

[Wolfgang Laun]

Usually a set of rules fires all rules when you call fireAllRules. So,
what's keeping you from collecting the solutions derived from the
fired rules and presenting them in some order to the user?

If the sequental addition or update of properties is interleaved with
calls to fireAllRules I'd attach a marker object "Refused" with each
rule resulting in a solution, and set its property to true when necessary.
