//
// Class ParticleInteractionBase
//   Base class for all particle-particle interactions.
//
//   Inheriting classes need to implement solve(), which evaluates all pairwise interactions between
//   particles. These (short-range) interaction happen on the particle container and its attributes
//   and not on a field.
