Iteration to determine stress state in each grain

An iterative procedure is required to find the solution for the stress state, sc, in each grain (at each step). Note that the strain rate (as a tensor) is imposed on each grain, i.e. boundary conditions based on strain.  Once a solution is found, then individual slipping rates (shear rates) can be calculated for each of the s slip systems.  The use of a rate sensitive formulation for yield avoids the necessity of ad hoc assumptions to resolve the ambiguity of slip system selection.

Within the LApp code, the relevant subroutines are SSS and NEWTON
