// Class Description
// Provides functions to calculate the nuclear radius as used in the
// abrasion-ablation model (see Wilson, Tripathi, Cucinotta et al, NASA
// Technical Paper 3533, October 1995), and to determine total nuclear-nuclear
// cross-sections.  The Algorithm comes from Tripathi, Cucinnota and Wilson,
// Nucl Instrum Meth Phys Res B, 152, pp425-431, 1999.
