Detailed Description

RootEvtSelector performs the function of controlling the ApplicationMgr loop.

Adapted to RootCnvSvc from GlastSvc/EventSelector. The input property can now be set either to NONE or to ROOT. If it is NONE, the loop will run until it hits EvtMax. A new class variable was added :m_evtMax which is a local copy of the AppMgrs property.
