DryScaleBoxFriction

DryScaleBoxFriction is DefaultDryFriction:
    .doc: """
    Defines a constant maximum friction forces,linear dof's, or torques, around angular dof's,
    given the current normal force between the involved two interacting bodies. 
    The difference between ScaleBox and Box friction is that ScaleBox defines the 
    maximum friction depending on the actual forces between the objects.
    There are obvious artifacts that comes with the ScaleBox method.
    First of all, it is anisotropic due to the box shape of the possible friction forces in the friction plane.
    The actual resulting friction forces is sqrt(2) times larger in the local XY direction than the X or Y direction.
    This issue is accounted for with the DryCone friction method, where a friction cone is computed.
    Another issue is the nonlinear behaviour, where in non-ideal situations, the normal and force depend on each other,
    and it is computationally very expensive to find a good solution.
