Detailed Description

Allows interactive navigation from event to event in cmsRun jobs. Just add the looper to the python configuration and then respond to the questions that show up on the display by typing a number followed by return.

This was originally written to test the looper interface used by the Fireworks event display. It might be useful by itself.

If you use this either do not use a PoolOutputModule or turn off fast cloning its configuration.
