Detailed Description

Description: Gets the state of the random number engines from the related service and stores it in the event.

Implementation: This simply copies from the cache in the service and puts the product in the Event and LuminosityBlock. The cache is filled at the beginning of processing for eac event or lumi by a call from the InputSource to the service. This module gets called later.
