FixedWeakConstraint. It is really a simplified version ofRestShapeSpringForcefieldthat only fixes points with respect to their rest_shape given one single value of stiffness. I didn't use an inheritance becauseRestShapeSpringForcefielddoes too much and the two set of features aren't really compatible. Keep it simple...This completes the holy trinity of fixed constraints, now we will have Weak, Projective and Langrangian fixed constraints. It unifies the mechanism.
