[rules-users] Using Rule Flow

[Mark Proctor]

I have just updated conways game of life example to use ruleflow, the 
agenda group one still exists. So execute ConwayAgendaGroupRun and 
ConwayRuleFlowGroupRun to run the two examples. AgendaGroupDelegate and 
RueFlowDelegate show the two different implementations.
