A linear 1D translational spring with unstretched length initialization.
The initial stretched spring length is given by parameter Ls and the unstretched spring length L0 is determined during intialization. Parameter dL0 is the difference between Ls and L0, which can be used to make a better starting guess for initialization (the default is 0.0).
The spring constant c is defined as the stiffness of a 1m spring. This is because the length of the spring is unknown until after initialization (i.e., the stiffness k=E*A/L cannot be determined until later). Therefore, the spring constant c is equivalent to c=E*A.
