//  HPionTrackerTaskSet
//
//  This HTaskSet contains the tasks for the PionTracker detector
//
//  Options:
//  - nopiontrackerhit: runs the task list only up to cal level (default: kTRUE)
//  - skipevents:       options for HPionTrackerHitF task (default: kFALSE)
//                      controls skipping of all events without successful
//                      time reconstruction.
