DryDepthScaledConstantNormalForceFriction

DryDepthScaledConstantNormalForceFriction is DryConstantNormalForceFriction:
    .doc: """
    The DryDepthScaledConstantNormalForceFriction extends the DryConstantNormalForceFriction model
    by scaling the normal force for each contact point by the depth of the point, depth_p, in meters.
    For varying elasticity of surface contacts, the geometrical overlap and therefore the contact point depths,
    may differ  alot. To maintain comparable friction inbetween these different surface contact models a
    depth_factor parameter is introduced.

    The friction limit, f_l, is always going to be:
    f_l = normal_force * depth_p * depth_factor * coefficient.

    The model must be considered VERY approximative, since it does not consider friction as
    a non-linear problem.
