Detailed Description

Member variable of #Particle storing all history parameters of a particle.

A tangential spring between PI and PJ can be stored in either particle depending on which particle is the first particle in MD::compute_internal_forces.

Geometrically, there can be no more than 13 possible contacts in 3D, so the vector size is limited.
