restructured algorithm: moved into loop to reallocate fields and replan FFTW in case resolution changes during runtime ==> regridding 

introduced parameters for selective debugging of spectral code and partly introduced the advanced divergence calculation again which is controlled by debug.config
added switch in numerics to control divergence behavior (uncorrected and corrected by phenomenological factor)
added precision directive to all values I found
