Detailed Description

This class represents an entry point to all the event specific data.

It is needed to make the algorithm "aware" of the event it is operating on. This was not needed in the serial version of Gaudi where the assumption of 1-event-at-the-time processing was implicit.

This class has nothing to do with the AlgContextSvc or the Context of the EvtSelector!
