In online mode, ROME often stops before finishing to analyze all events of runs. 
 When it happens, gAnalyzer->GetCurrentEventNumber() starts not from 1 but from analyzed event 
number at previous run. And unanalyzed events at the previous run are mixed with the new run.

In mana.c of MIDAS, I found a part to wait until all events in buffers are analyzed when analyzer gets 
TR_STOP signal, while ROME does not have.

I personaly don't need that all events are analyzed, but it is really problem that data of two runs are 
mixed.

One way is to take similar way as midas analyzer, and the another way is just discard unanalyzed 
events.
