Add a helper for intra-nucleus nucleon-nucleon collisions

Add TwodGridBuilder and angular distribution data for sampling cos\theta of the intra-nucleus nucleon-nucleon scattering.
Add CascadeCollider and CascadeParticle for sampling the final state of the ntra-nucleus cascade collision and an associated test.
Add namespace lorentz for FourVector and a couple of utility functions

@sethrj Thanks a lot for all review comments. Will follow up later today! Regarding to vec4 --> momentum, I will think an alternative as a component of FourVector is mom (three vector), which is confusing with the proposed momentum (four vector). Maybe changing FourVector(mom, energy) --> (p, e) and then vec4 --> momentum or mom. Welcome to the 4-momentum world^^.
