merged calcmodes, i.e. equilibrium and fulfilling of stress BC is done in one step, made convergence independent of size and resolution, polishing output in DAMASK_spectral.f90 added function to compute eigenvalues without eigenvectors and function to convert a 3x3 logical to a 9 vector in math.f90 removed obsolete variable in numerics.f90

added some switches and variables to the makefile to make it more flexible DAMASK_spectral.f90 is a "debug version" with a number of different criteria to determine divergence. will be removed later on.

added fftw3 as fft(library will not versioned, should be in a linkable folder) , did some corrections on the code, splitted main file up (allows use of makefile), added makefile changes on mpie_spectral.f90: new structure, changed variable names, now using defgrad instead of disgrad, cleaned up, removed augmented Lagrange. ToDo: Implement Augmented Lagrange again (but then a working version), implement Large strain, think about complex-to real-transform backwards, try to implement MP-support
