# separated CPFEM_Crystallite from CPFEM. Now in separate module crystallite.f90 as "SingleCrystallite"
...
# improved SingleCrystallite to advance by true cutbacking (instead of improving guess and integrating always from t_0)
# module "crystal" renamed to "lattice" together with its prefix for variables
# extension of "computationMode" to deal with cutbacks (CPFEM_general).
# cutback and new inc detection for MARC is based on common block variable cptim (and inc), not incsub anymore!
# generalized GrainInterAction as new homogenization scheme
# two symbolic links are required: constitutive.f90 and CPFEM.f90
