[rules-users] Using multiple RuleFlows with similar group names

[Mark Proctor]

There is a loose coupling from the ruleflow-group defined in the drl and 
the one in the ruleflow. So no matter how many rules you add, and how 
they are added, there will only be one ruleflow-group "Group A". You can 
deploy two ruleflows, both that use that group. The process that enters 
that group first will then be in charge of executing the rules - you 
should make sure there is no overlap in execution, I'm not sure what hte 
behaviour would be then; i.e. the second ruleflow attempts to activate 
the same group that the first ruleflow is already executing.
