Clear all data members
Impact parameter
Determine impact parameter for each nucleus
No repulsion, just store (r,theta,phi)
Store first nucleon, and increment total
Check all the nucleons stored whether there are overlap each other defined by mRepulsionDistance. If any nucleons overlap, then discard current nucleon and try again
Determine Number of collisions by looping over all pair of nucleons
Need at least one Ncoll
Determine Npart Calculate <x>, <y>, <x^2>, <y^2>, <xy>, ecc_{RP} and ecc_{PP}
