\class    genie::PauliBlocker

\brief    Examines whether the generated event should be Pauli blocked.
          Is a concerete implementation of the EventRecordVisitorI interface.

          Changes required to implement the GENIE Boosted Dark Matter module
          were installed by Josh Berger (Univ. of Wisconsin)

          Other code improvements, additions, fixes were installed by
          Joe Johnston (Univ of Pittsburgh)
