Numerous changes to use and compute initial stresses to be stored in state0 array.  Updating of elastic and time-dependent stresses has been changed to reflect initial stresses, and the prestress computation routine has been altered to make use of user-specified initial values for Poisson's ratio and Young's modulus, if desired. A new formulation, based on an effective stress function formulation, has been employed for stress computation and tangent stress-strain matrix computation.  The stress computation takes initial stresses into account.
