/** FairEventBuffer
 *@author Radoslaw Karabowicz <r.karabowicz@gsi.de>
 *@since 23/09/2013
 *@version 1.0
 **
 ** FairRoot base task for the event buffers. 
 ** The tasks may:
 ** 1. analyze data to reconstruct event times or other characteristics
 **    in the function TClonesArray* FindEvents(), that returns
 **    TClonesArray of FairRecoEvents
 ** 2. identify the data that could belong to event in the 
 **    function and insert this identified data to the output TClonesArrays
 **    in the function StoreEventData(event)
 ** The implementations may be using any or both of the above functions.
