 * @brief Accumulable of Dose-related data (that must be thread-local).
 *
 * It keeps the energy deposit data divided in voxels for dose calculation
 *
 * This is implemented as a customized G4VAccumulable with non-scalar data.
 *
 * @note There are two levels of merging (accumulation):
 *   1) From more threads in one run (G4VAccumulable merging is applied)
 *   2) (Optional) inter-run merging of data (implemented in Dose).
 *
 * @note std::valarray is used (instead of C arrays or std::vectors)
 *    to accumulate data for its logical simplicity.
