Functionality for calculating Coulomb parameters for different configurations. Including a number of functions for handling Coulomb collisions spanning weakly coupled (low density) to strongly coupled (high density) regimes.

Coulomb collisions are collisions where the interaction force is conveyed via the electric field, instead of any kind of contact force. They usually result in relatively small deflections of particle trajectories. However, given that there are many charged particles in a plasma, one has to take into account the cumulative effects of many such collisions.
