In the client-side GUI version of Kepler we open/run workflows and reports like
so:
1-Open KAR (contains the workflow and the report layout)
2-Run the workflow (which generates the report when completed and writes it to
provenance)
3-Export the run as KAR (contains the workflow that was run, the report layout,
the report instance (xml) and a pdf of the report instance).

The execution engine needs to open the workflow from the KAR so that the report
layout is available. I believe the current plan _only_ involves the workflow
LSID and does not address any report layout issues.

I'd like to see an execution method that can take a KAR LSID (that contains a
workflow and a report layout). It would then perform the three steps above. 

Note that the KAREntryHandlers take care of the opening/initializing steps for
reporting to work - so that's good (and already built in)!
