Detailed Description

Event store which fills entries to an own root TTree in a TFile.

In contrast to TreeStore, we do not use the main go4 tree, but an independent one which need not correspond with the entry indices of all previous events. Disadvantage: difficult to correlate to input events; advantage: one entry of this tree may be composed from several subsequent input event entries...
