[rules-users] drl execution problem

[Michael Anstis]

e.g. add an ID field to Person that is incremental in value on subsequent
"people"

person1: Person( $firstName1: firstName, $id : id )
person2: Person( firstName != $firstName1, id > $id )

This ensures only one match of person1 and person2 will occur, not person2
and person1.
