//
//
//
//
/// Construction of a target material (default = boron) surrounded by a
///     casing material (default = water) and a vacuum world (default =
///     target and casing fill world). The target + casing is brick
///     geometry with fTargetSections defining the number of divisions
///     in each dimension. The end sections in each dimension
///     is set to the casing. So a fTargetSections = G4ThreeVector(3, 3, 3)
///     would be one section of boron and 8 sections of water.
/// The idea behind this geometry is just to create a simple geometry that
///     scatters and produces a lot neutrons with a minimal number of sections
///     (i.e. coarse meshing) such that the contention in operating on
///     the atomic hits maps is higher and round-off errors in the
///     thread-local hits maps are detectable (printed out in TSRunAction)
///     from the sheer number of floating point sum operations.
/// Two scorers are implemented: EnergyDeposit and Number of steps
///     The energy deposit is to (possibly) show the round-off error seen
///     with thread-local hits maps. The # of steps scorer is to verify
///     the thread-safe and thread-local hits maps provide the same results.
