* class SoftBodySimulation is derived from class Simulation (see Physics1.h).
* It simulates a softbody with point-like particles binded with springs. The
* springs have inner friction and normal length. One tip of the softbody is
* stabilized at a point in space called "Vector3D softbodyConnectionPos".
* This point can be moved externally by a method
* "void setSoftBodyConnectionVel(Vector3D softbodyConnectionVel)". SoftBodySimulation
* creates air friction and a planer surface (or ground) with a
* normal in +y direction. SoftBodySimulation implements the force applied
* by this surface. In the code, the surface is refered as "ground".
