Detailed Description

GenericFragmentSimulator creates simulated Generic events, with data distributed according to a "histogram" provided in the configuration data.

With this implementation, a single call to getNext(frags) will return a complete event (event ids are incremented automatically); fragment ids are sequential. Event size and content are both configurable; see the implementation for details.
