>Once the potential interactions are determined (so a lot of couple of bodies 
which will surely not interact are disregarded) it is investigated if the 
bodies are really in contact or not (see flag isReal later), thanks to 
InteractionGeometryMetaEngine.

>After that, the physical properties of the interactions, which will be used 
to compute contact forces (rigidities...) are set by 
InteractionPhysicsMetaEngine which uses classes containing the parameters of 
bodies and classes describing how to compute interactions properties from 
bodies properties (names finishing by ...RelationsShips). 

On the contrary. The first is InteractionPhysics (unique for each pair of 
bodies, calculated at detecting potential contact), then InteractionGeometry 
(calculated for the real contacts)...
