//  TPC   - analyzes TPC   tracking + particles corresponding to these tracks
//  ITSv1 - analyzes ITSv1 ----------------------//--------------------------
//  ITSv2 - analyzes ITSv2 ----------------------//--------------------------

//processopt defines option passed to AliHBTAnlysis::Process method
// default: TracksAndParticles - process both recontructed tracks and sim. particles corresponding to them 
//          Tracks - process only recontructed tracks
//          Particles - process only simulated particles

//Reads data from diroctories from first to last(including)
// For examples if first=3 and last=5 it reads from
//  ./3/
//  ./4/
//  ./5/
//if first or last is negative (or both), it reads from current directory
//
//these names I use when analysis is done directly from CASTOR files via RFIO
