 *
 * \brief Task to flag or to remove tracks with missing Pz information
 *
 * This task takes as an input any PndTrack branch. It goes through all the tracks. For those tracks only consisting of STTHits
 * and with a ParamFirst::pz value between 0.015 and 0.025 it either sets the PndTrack::fFlag to -30 or deletes the track.
 * What action is taken is selected by SetRemoveTrack(). If SetRemoveTrack is set to kTRUE the track is deleted otherwise flaged.
 * The filtered PndTracks are written in an output branch either with a given name by SetOutputTrackBranch() of, if no branch name is
 * given by InputTrackBranchName + "_filtered".
