// Description:
//      Data class for the Digitization. (Transient)
//      Represents primary clusters of electrons which are created
//      by the passage of a charged particle through the TPC gas-volume

//      Created by: PndTpcClusterizerTask
//      Used by:    PndTpcDrifterTask
//
//
// Environment:
//      Software developed for the PANDA Detector at FAIR.
