//  AliLevel3
//
//  Interface class for Level3 tracker.
//  Tracking is done by calling constructor with input,output 
//  given as argument. 
//  You must always remember to set the tracking parameters. E.g.:
// 
//  AliLevel3 *level3 = new AliLevel3(inputfile,outputfile);
//  level3->SetTrackerParam(); //Sets default tracking parameters
//  level3->ProcessSector(2,2);  //Does tracking on sector 2 (actually 2+38)
