/// \file TSRun.hh
/// \brief Definition of the TSRun class
///
/// TSRun contains three collections of hits maps: a thread-local hits map,
///     a global atomic hits map (implemented as a static since TSRun is
///     implemented as a thread-local instance), and a global "mutex" hits map
///     (also implemented as a static). The thread-local hits map is the
///     same as you will find in many other examples. The atomics hits map
///     is the purpose of this example. Code-wise, the implementation looks
///     extremely similar to the thread-local version with the 3 primary
///     exceptions: (1) construction - there should only be one instance so
///     it should be a static member variable or a pointer/reference to a
///     single instance elsewhere in the code (stored in ActionInitialization,
///     for instance); (2) It does not need to, nor should be, summed in
///     G4Run::Merge(); and (3) destruction -- it should only be cleared by
///     the master thread since there is only one instance.
///
/// A "mutex" hits map is also included as reference for checking the results
///     accumulated by the thread-local hits maps and atomic hits maps. The
///     differences w.r.t. this hits maps are computed in
///     TSRunAction::EndOfRunAction
//
