ContactMechanical class.
Mechanical Contacts may exist between two IPiece objects (e.g. between two balls or between a ball and a wall). They are formed and broken automatically during the course of a simulation.
The behavior of a material is simulated by associating a constitutive model with each mechanical contact.
