[rules-dev] recursion checking util

[Mark Proctor]

I've been getting requests for a testing tool that checks for recursion, 
and exits the test if its detected. Any takers fancy having a go at 
this? Mostly its just an event model thing, bit like the audit view. But 
as recursion is not just about rule recursion, but Activation recursion 
too (i.e. rule recursion with the same data), you'll need to create a 
stack of rules and tuples, and check against that stack for possible 
recursions. Should be fun :)
