----------------------------------

Opened PIG-2678 for creating an abstract PPNL. Unless anyone else has comments, I'll commit
patch #2.

> The {{PigProgressNotificationListner}} should get notified of the plan ({{MROperPlan}})
before it gets executed. This allows listeners to inspect the plan and have an idea what to
expect in the execution flow. Proposal is to add the following method to the PPNL interface,
which is marked as evolving:
> {code}
> public void initialPlanNotification(MROperPlan plan);
> {code}
