Added a new input file and two new slip model files. A new function 'okadaCoeff_mpi()' has been implemented that is an attempt at MPI parallelization of the okadaCoeff() function. The implementation does not work correctly. There appears to be a problem with using MPI_Allgather() on the f3tensor. This needs to be tested and fixed.
Updated the code so that the currently under development MPI parallelization for okadaCoeff_mpi() is not executed.
